Redistricting is the process by which new congressional and state legislative district boundaries are drawn. Each of New Mexico's three United States Representatives and 112 state legislators are elected from political divisions called districts. United States Senators are not elected by districts, but by the states at large. District lines are redrawn every 10 years following completion of the United States census. The federal government stipulates that districts must have nearly equal populations and must not discriminate on the basis of race or ethnicity.[1][2][3][4]

New Mexico was apportioned 3 seats in the U.S. House of Representatives after the 2020 census, the same number it received after the 2010 census. Click here for more information about redistricting in New Mexico after the 2020 census.

HIGHLIGHTS
  • Following the 2020 United States Census, New Mexico was apportioned three congressional districts, which was unchanged from the number it had after the 2010 census.
  • New Mexico's House of Representatives is made up of 70 districts; New Mexico's State Senate is made up of 42 districts.
  • In New Mexico, both congressional and state legislative district boundaries are drawn by the state legislature.
  • On December 17, 2021, Gov. Michelle Lujan Grisham signed new a congressional map into law.[5] The New Mexico State Senate approved the bill 25-15 on December 10, 2021, and the New Mexico House of Representatives approved the bill 44-24 on December 11, 2021.[6] The map was based on the New Mexico Citizen Redistricting Committee's H congressional map concept. This map took effect for New Mexico's 2022 congressional elections. On November 27, 2023, the New Mexico Supreme Court upheld the state's congressional map and dismissed the remaining litigation against it.[7] Gov. Michelle Lujan Grisham (D) signed a new state House map into law on December 29, 2021, and a new state Senate map on January 6, 2022. These maps took effect for New Mexico's 2022 legislative elections. The state House approved the House map bill 43-23 on December 10, 2021, and the state Senate approved the bill 24-13 on December 16, 2021.[8] The state Senate approved the Senate map 25-13 on December 16, and the state House approved the map 38-22 on December 17.[9] Click here for more information on maps enacted after the 2020 census.

    Background

    This section includes background information on federal requirements for congressional redistricting, state legislative redistricting, state-based requirements, redistricting methods used in the 50 states, gerrymandering, and recent court decisions.

    Federal requirements for congressional redistricting

    According to Article I, Section 4 of the United States Constitution, the states and their legislatures have primary authority in determining the "times, places, and manner" of congressional elections. Congress may also pass laws regulating congressional elections.[10][11]

    The Times, Places and Manner of holding Elections for Senators and Representatives, shall be prescribed in each State by the Legislature thereof; but the Congress may at any time by Law make or alter such Regulations, except as to the Places of chusing Senators.[12]
    —United States Constitution

    Article I, Section 2 of the United States Constitution stipulates that congressional representatives be apportioned to the states on the basis of population. There are 435 seats in the United States House of Representatives. Each state is allotted a portion of these seats based on the size of its population relative to the other states. Consequently, a state may gain seats in the House if its population grows or lose seats if its population decreases, relative to populations in other states. In 1964, the United States Supreme Court ruled in Wesberry v. Sanders that the populations of House districts must be equal "as nearly as practicable."[13][14][15]

    The equal population requirement for congressional districts is strict. According to All About Redistricting, "Any district with more or fewer people than the average (also known as the 'ideal' population), must be specifically justified by a consistent state policy. And even consistent policies that cause a 1 percent spread from largest to smallest district will likely be unconstitutional."[15]

    Federal requirements for state legislative redistricting

    The United States Constitution is silent on the issue of state legislative redistricting. In the mid-1960s, the United States Supreme Court issued a series of rulings in an effort to clarify standards for state legislative redistricting. In Reynolds v. Sims, the court ruled that "the Equal Protection Clause [of the United States Constitution] demands no less than substantially equal state legislative representation for all citizens, of all places as well as of all races." According to All About Redistricting, "it has become accepted that a [redistricting] plan will be constitutionally suspect if the largest and smallest districts [within a state or jurisdiction] are more than 10 percent apart."[15]

    State-based requirements

    In addition to the federal criteria noted above, individual states may impose additional requirements on redistricting. Common state-level redistricting criteria are listed below.

    1. Contiguity refers to the principle that all areas within a district should be physically adjacent. A total of 49 states require that districts of at least one state legislative chamber be contiguous (Nevada has no such requirement, imposing no requirements on redistricting beyond those enforced at the federal level). A total of 23 states require that congressional districts meet contiguity requirements.[15][16]
    2. Compactness refers to the general principle that the constituents within a district should live as near to one another as practicable. A total of 37 states impose compactness requirements on state legislative districts; 18 states impose similar requirements for congressional districts.[15][16]
    3. A community of interest is defined by FairVote as a "group of people in a geographical area, such as a specific region or neighborhood, who have common political, social or economic interests." A total of 24 states require that the maintenance of communities of interest be considered in the drawing of state legislative districts. A total of 13 states impose similar requirements for congressional districts.[15][16]
    4. A total of 42 states require that state legislative district lines be drawn to account for political boundaries (e.g., the limits of counties, cities, and towns). A total of 19 states require that similar considerations be made in the drawing of congressional districts.[15][16]

    Methods

    In general, a state's redistricting authority can be classified as one of the following:[17]

    1. Legislature-dominant: In a legislature-dominant state, the legislature retains the ultimate authority to draft and enact district maps. Maps enacted by the legislature may or may not be subject to gubernatorial veto. Advisory commissions may also be involved in the redistricting process, although the legislature is not bound to adopt an advisory commission's recommendations.
    2. Commission: In a commission state, an extra-legislative commission retains the ultimate authority to draft and enact district maps. A non-politician commission is one whose members cannot hold elective office. A politician commission is one whose members can hold elective office.
    3. Hybrid: In a hybrid state, the legislature shares redistricting authority with a commission.

    Gerrymandering

    In 1812, Massachusetts Governor Elbridge Gerry signed into law a state Senate district map that, according to the Encyclopædia Britannica, "consolidated the Federalist Party vote in a few districts and thus gave disproportionate representation to Democratic-Republicans." The word gerrymander was coined by The Boston Gazette to describe the district.
    See also: Gerrymandering

    The term gerrymandering refers to the practice of drawing electoral district lines to favor one political party, individual, or constituency over another. When used in a rhetorical manner by opponents of a particular district map, the term has a negative connotation but does not necessarily address the legality of a challenged map. The term can also be used in legal documents; in this context, the term describes redistricting practices that violate federal or state laws.[1][18]

    The phrase racial gerrymandering refers to the practice of drawing electoral district lines to dilute the voting power of racial minority groups. Federal law prohibits racial gerrymandering and establishes that, to combat this practice and to ensure compliance with the Voting Rights Act, states and jurisdictions can create majority-minority electoral districts. A majority-minority district is one in which a racial group or groups comprise a majority of the district's populations. Racial gerrymandering and majority-minority districts are discussed in greater detail in this article.[19]

    The phrase partisan gerrymandering refers to the practice of drawing electoral district maps with the intention of favoring one political party over another. In contrast with racial gerrymandering, on which the Supreme Court of the United States has issued rulings in the past affirming that such practices violate federal law, the high court had not, as of November 2017, issued a ruling establishing clear precedent on the question of partisan gerrymandering. Although the court has granted in past cases that partisan gerrymandering can violate the United States Constitution, it has never adopted a standard for identifying or measuring partisan gerrymanders. Partisan gerrymandering is described in greater detail in this article.[20][21]

    Recent court decisions

    See also: Redistricting cases heard by the Supreme Court of the United States

    The Supreme Court of the United States has, in recent years, issued several decisions dealing with redistricting policy, including rulings relating to the consideration of race in drawing district maps, the use of total population tallies in apportionment, and the constitutionality of independent redistricting commissions. The rulings in these cases, which originated in a variety of states, impact redistricting processes across the nation.

    Gill v. Whitford (2018)

    See also: Gill v. Whitford

    In Gill v. Whitford, decided on June 18, 2018, the Supreme Court of the United States ruled that the plaintiffs—12 Wisconsin Democrats who alleged that Wisconsin's state legislative district plan had been subject to an unconstitutional gerrymander in violation of the First and Fourteenth Amendments—had failed to demonstrate standing under Article III of the United States Constitution to bring a complaint. The court's opinion, penned by Chief Justice John Roberts, did not address the broader question of whether partisan gerrymandering claims are justiciable and remanded the case to the district court for further proceedings. Roberts was joined in the majority opinion by Associate Justices Anthony Kennedy, Ruth Bader Ginsburg, Stephen Breyer, Samuel Alito, Sonia Sotomayor, and Elena Kagan. Kagan penned a concurring opinion joined by Ginsburg, Breyer, and Sotomayor. Associate Justice Clarence Thomas penned an opinion that concurred in part with the majority opinion and in the judgment, joined by Associate Justice Neil Gorsuch.[22]

    Cooper v. Harris (2017)

    See also: Cooper v. Harris

    In Cooper v. Harris, decided on May 22, 2017, the Supreme Court of the United States affirmed the judgment of the United States District Court for the Middle District of North Carolina, finding that two of North Carolina's congressional districts, the boundaries of which had been set following the 2010 United States Census, had been subject to an illegal racial gerrymander in violation of Section 2 of the Voting Rights Act. Justice Elena Kagan delivered the court's majority opinion, which was joined by Justices Clarence Thomas, Ruth Bader Ginsburg, Stephen Breyer, and Sonia Sotomayor (Thomas also filed a separate concurring opinion). In the court's majority opinion, Kagan described the two-part analysis utilized by the high court when plaintiffs allege racial gerrymandering as follows: "First, the plaintiff must prove that 'race was the predominant factor motivating the legislature's decision to place a significant number of voters within or without a particular district.' ... Second, if racial considerations predominated over others, the design of the district must withstand strict scrutiny. The burden shifts to the State to prove that its race-based sorting of voters serves a 'compelling interest' and is 'narrowly tailored' to that end." In regard to the first part of the aforementioned analysis, Kagan went on to note that "a plaintiff succeeds at this stage even if the evidence reveals that a legislature elevated race to the predominant criterion in order to advance other goals, including political ones." Justice Samuel Alito delivered an opinion that concurred in part and dissented in part with the majority opinion. This opinion was joined by Chief Justice John Roberts and Justice Anthony Kennedy.[23][24][25]

    Evenwel v. Abbott (2016)

    See also: Evenwel v. Abbott

    Evenwel v. Abbott was a case decided by the Supreme Court of the United States in 2016. At issue was the constitutionality of state legislative districts in Texas. The plaintiffs, Sue Evenwel and Edward Pfenninger, argued that district populations ought to take into account only the number of registered or eligible voters residing within those districts as opposed to total population counts, which are generally used for redistricting purposes. Total population tallies include non-voting residents, such as immigrants residing in the country without legal permission, prisoners, and children. The plaintiffs alleged that this tabulation method dilutes the voting power of citizens residing in districts that are home to smaller concentrations of non-voting residents. The court ruled 8-0 on April 4, 2016, that a state or locality can use total population counts for redistricting purposes. The majority opinion was penned by Justice Ruth Bader Ginsburg.[26][27][28][29]

    Harris v. Arizona Independent Redistricting Commission (2016)

    Justice Stephen Breyer penned the majority opinion in Harris v. Arizona Independent Redistricting Commission.
    See also: Harris v. Arizona Independent Redistricting Commission

    Harris v. Arizona Independent Redistricting Commission was a case decided by the Supreme Court of the United States in 2016. At issue was the constitutionality of state legislative districts that were created by the commission in 2012. The plaintiffs, a group of Republican voters, alleged that "the commission diluted or inflated the votes of almost two million Arizona citizens when the commission intentionally and systematically overpopulated 16 Republican districts while under-populating 11 Democrat districts." This, the plaintiffs argued, constituted a partisan gerrymander. The plaintiffs claimed that the commission placed a disproportionately large number of non-minority voters in districts dominated by Republicans; meanwhile, the commission allegedly placed many minority voters in smaller districts that tended to vote Democratic. As a result, the plaintiffs argued, more voters overall were placed in districts favoring Republicans than in those favoring Democrats, thereby diluting the votes of citizens in the Republican-dominated districts. The defendants countered that the population deviations resulted from legally defensible efforts to comply with the Voting Rights Act and obtain approval from the United States Department of Justice. At the time of redistricting, certain states were required to obtain preclearance from the U.S. Department of Justice before adopting redistricting plans or making other changes to their election laws—a requirement struck down by the United States Supreme Court in Shelby County v. Holder (2013). On April 20, 2016, the court ruled unanimously that the plaintiffs had failed to prove that a partisan gerrymander had taken place. Instead, the court found that the commission had acted in good faith to comply with the Voting Rights Act. The court's majority opinion was penned by Justice Stephen Breyer.[30][31][32]

    Arizona State Legislature v. Arizona Independent Redistricting Commission (2015)

    See also: Arizona State Legislature v. Arizona Independent Redistricting Commission
    Arizona State Legislature v. Arizona Independent Redistricting Commission was a case decided by the Supreme Court of the United States in 2015. At issue was the constitutionality of the Arizona Independent Redistricting Commission, which was established by state constitutional amendment in 2000. According to Article I, Section 4 of the United States Constitution, "the Times, Places and Manner of holding Elections for Senators and Representatives shall be prescribed in each State by the Legislature thereof." The state legislature argued that the use of the word "legislature" in this context is literal; therefore, only a state legislature may draw congressional district lines. Meanwhile, the commission contended that the word "legislature" ought to be interpreted to mean "the legislative powers of the state," including voter initiatives and referenda. On June 29, 2015, the court ruled 5-4 in favor of the Arizona Independent Redistricting Commission, finding that "redistricting is a legislative function, to be performed in accordance with the state's prescriptions for lawmaking, which may include the referendum and the governor's veto." The majority opinion was penned by Justice Ruth Bader Ginsburg and joined by Justices Anthony Kennedy, Stephen Breyer, Elena Kagan, and Sonia Sotomayor. Chief Justice John Roberts and Justices Clarence Thomas, Antonin Scalia, and Samuel Alito dissented.[33][34][35][36]

    Race and ethnicity

    See also: Majority-minority districts

    Section 2 of the Voting Rights Act of 1965 mandates that electoral district lines cannot be drawn in such a manner as to "improperly dilute minorities' voting power."

    No voting qualification or prerequisite to voting, or standard, practice, or procedure shall be imposed or applied by any State or political subdivision to deny or abridge the right of any citizen of the United States to vote on account of race or color.[12]
    —Voting Rights Act of 1965[37]

    States and other political subdivisions may create majority-minority districts in order to comply with Section 2 of the Voting Rights Act. A majority-minority district is a district in which minority groups compose a majority of the district's total population. As of 2015, New Mexico was home to three congressional majority-minority districts.[2][3][4]

    Proponents of majority-minority districts maintain that these districts are a necessary hindrance to the practice of cracking, which occurs when a constituency is divided between several districts in order to prevent it from achieving a majority in any one district. In addition, supporters argue that the drawing of majority-minority districts has resulted in an increased number of minority representatives in state legislatures and Congress.[2][3][4]

    Critics, meanwhile, contend that the establishment of majority-minority districts can result in packing, which occurs when a constituency or voting group is placed within a single district, thereby minimizing its influence in other districts. Because minority groups tend to vote Democratic, critics argue that majority-minority districts ultimately present an unfair advantage to Republicans by consolidating Democratic votes into a smaller number of districts.[2][3][4]


    State process

    See also: State-by-state redistricting procedures

    In New Mexico, congressional and state legislative district boundaries are drawn by the state legislature. These lines are subject to veto by the governor.[38]

    State statutes require that state legislative districts be contiguous and compact. Redistricting guidelines adopted in 2011 suggest that congressional and state legislative districts meet the following criteria:[38]

    1. All districts should be "reasonably compact."
    2. Districts should "not split voting precincts."
    3. Districts should "attempt to preserve communities of interest and take into consideration political and geographic boundaries."

    These guidelines are nonbinding and may be altered by the legislature at its discretion.[38]

    On April 6, 2021, Governor Michelle Lujan Grisham (D) signed SB304 into law, forming a seven-member advisory redistricting commission. The legislation bars public officials, candidates, political party officeholders, federal legislative or state employees, and the relatives of federal or state officeholders from serving on the commission. The commission's proposals do not bind the state legislature, which retains the authority to adopt, amend, or discard the proposals as it sees fit.[39]

    Reactions

    Steve Pearce, chairman of the New Mexico Republican Party, criticized the map, saying: "these maps are far from fair representation, and they are a disservice to constituents. The real losers are the rural voices of New Mexico, conservative Democrats, Republicans, and independents."[44] State Senate Majority Leader Peter Wirth (D) said: "The new congressional map creates districts where we have to work together — rural and urban, north and south, and Democrats, Republicans and independents. That is a good thing."[44]

    Reactions

    After signing the state House map into law, Gov. Michelle Lujan Grisham (D) said the map was a "sound map that is representative and respectful of New Mexico’s varied communities of interest and will, I believe, ensure that the will of the people will continue to be done in that chamber." The Albuquerque Journal wrote: "Republican lawmakers vigorously objected to the map during the special session earlier this month. They said it creates a political advantage for Democrats, and they sought to change some boundaries to help Republican Rep. Jane Powdrell-Culbert of Corrales."[47]

    After signing the state Senate map, Lujan Grisham said: "I am grateful to the community leaders from across the state that held their ground for a representative map respectful of New Mexico communities large and small alike, ensuring that New Mexicans are fairly represented in the state Senate."[48] The Albuquerque Journal wrote: "The map also pairs two Hispanic Republicans – Senate Minority Leader Greg Baca of Belen and Sen. Joshua Sanchez of Bosque – into one district, forcing them to either move or run against each other in 2024 to keep a legislative seat. During last month’s testy Senate floor debate on the new map, Baca called the plan racist and said Hispanic residents were being 'cheated of your seats.'"[49]


    Redistricting after the 2010 census

    Congressional redistricting, 2010

    Following the 2010 United States Census, New Mexico neither gained nor lost congressional seats. At the time of redistricting, Democrats controlled both chambers of the state legislature, but a Republican held the governorship. On September 19, 2011, the Senate approved a congressional redistricting plan, but the legislature adjourned before the map could be taken up for a vote in the House. The New Mexico Supreme Court assigned a retired judge, James Hall, to draw the final congressional map. On December 29, 2011, the final map was issued.[38][50]

    State legislative redistricting, 2010

    On September 23, 2011, the legislature approved redistricting plans for the state Senate and House, but these were vetoed by the governor on October 7, 2011. The matter was brought before the New Mexico First Judicial District Court, which issued an opinion establishing new state House district lines on January 3, 2012. On February 10, 2012, the New Mexico Supreme Court ruled that the state House maps must be redrawn, "with instructions for the trial court to reconsider the extent to which mildly larger population deviations would satisfy other state redistricting criteria, to reconsider the partisan impact and incumbent pairings of a court-ordered plan, and to recognize a district protecting Hispanic voters in the Clovis area under the Voting Rights Act." On February 27, 2012, the New Mexico First Judicial District Court issued its second state House redistricting plan, which stood.[38]

    On January 16, 2012, the New Mexico First Judicial District Court established new state Senate district lines. The court-issued redistricting plan "focused on minimizing population deviation, and drawing districts to allow Native Americans an effective opportunity to elect candidates of choice under the Voting Rights Act. The court found no need, under the totality of circumstances, to draw maps specifically protecting Hispanic voters under the Voting Rights Act."[38]

    Political impacts of redistricting

    Competitiveness

    There are conflicting opinions regarding the correlation between partisan gerrymandering and electoral competitiveness. In 2012, Jennifer Clark, a political science professor at the University of Houston, said, "The redistricting process has important consequences for voters. In some states, incumbent legislators work together to protect their own seats, which produces less competition in the political system. Voters may feel as though they do not have a meaningful alternative to the incumbent legislator. Legislators who lack competition in their districts have less incentive to adhere to their constituents’ opinions."[51]

    In 2006, Emory University professor Alan Abramowitz and Ph.D. students Brad Alexander and Matthew Gunning wrote, "[Some] studies have concluded that redistricting has a neutral or positive effect on competition. ... [It] is often the case that partisan redistricting has the effect of reducing the safety of incumbents, thereby making elections more competitive."[52]

    In 2011, James Cottrill, a professor of political science at Santa Clara University, published a study of the effect of non-legislative approaches (e.g., independent commissions, politician commissions) to redistricting on the competitiveness of congressional elections. Cottrill found that "particular types of [non-legislative approaches] encourage the appearance in congressional elections of experienced and well-financed challengers." Cottrill cautioned, however, that non-legislative approaches "contribute neither to decreased vote percentages when incumbents win elections nor to a greater probability of their defeat."[53]

    In 2021, John Johnson, Research Fellow in the Lubar Center for Public Policy Research and Civic Education at Marquette University, reviewed the relationship between partisan gerrymandering and political geography in Wisconsin, a state where Republicans have controlled both chambers of the state legislature since 2010 while voting for the Democratic nominee in every presidential election but one since 1988. After analyzing state election results since 2000, Johnson wrote, "In 2000, 42% of Democrats and 36% of Republicans lived in a neighborhood that the other party won. Twenty years later, 43% of Democrats lived in a place Trump won, but just 28% of Republicans lived in a Biden-voting neighborhood. Today, Democrats are more likely than Republicans to live in both places where they are the overwhelming majority and places where they form a noncompetitive minority."[54]

    In 2014, Ballotpedia conducted a study of competitive districts in 44 state legislative chambers between 2010, the last year in which district maps drawn after the 2000 census applied, and 2012, the first year in which district maps drawn after the 2010 census applied. Ballotpedia found that there were 61 fewer competitive general election contests in 2012 than in 2010. Of the 44 chambers studied, 25 experienced a net loss in the number of competitive elections. A total of 17 experienced a net increase. In total, 16.2 percent of the 3,842 legislative contests studied saw competitive general elections in 2010. In 2012, 14.6 percent of the contests studied saw competitive general elections. An election was considered competitive if it was won by a margin of victory of 5 percent or less. An election was considered mildly competitive if it was won by a margin of victory between 5 and 10 percent. For more information regarding this report, including methodology, see this article.

    In New Mexico, there were nine competitive races for the New Mexico House of Representatives in 2012, compared to five in 2010. There were six mildly competitive House races in 2012, compared to five in 2010. This amounted to a net gain of five competitive elections.
