Redistricting

A look at how things might play out in two key states — Texas & Wisconsin — in the redistricting tug of wars
In Wisconsin, though the state Supreme Court justices recently said they would not hear the congressional redistricting case before them, a new lawsuit has been filed.
A group called the Wisconsin Business Leaders for Democracy filed the lawsuit claiming the current map is an “anti-competitive gerrymander,” distinguishing their claim from the partisan gerrymander lawsuit the Supreme Court refused to hear according to an Associated Press news story. An anti-competitive gerrymander refers to all incumbents rather than those of one particular party.
The Wisconsin suit was filed in before a Dane County circuit court where the plaintiffs will likely get a favorable ruling. The process, however, will be lengthy as appeals to any lower court ruling will occur before again reaching the state Supreme Court. Therefore, it may be a longshot to see the Wisconsin map redrawn before the 2026 midterm elections.
The Texas situation is much different, and Republican leaders may be able to produce a new map that increases the current plan’s 25R-13D split.
South Texas appears to attract the most attention in the special session. Using the Dave’s Redistricting App statisticians’ partisan lean calculations (methodology employed to develop the partisan lean figures can be found on the following “About Data” link from the DRA website: About Data – Dave’s Redistricting App), we generally see the Republicans overperforming in the region.
Under the current Texas plan, the DRA partisan lean calculation correctly projected which party would hold the particular congressional district in 37 of the 38 CDs. The only officeholder to win a congressional seat where the opposing party held the partisan lean advantage occurred in South Texas District 15 where two-term GOP Rep. Monica de la Cruz (R-McAllen) held her seat with a 57-43 percent majority. The DRA 15th District partisan calculation gives the Democrats a 4.1 percentage point advantage.
President Trump carried 27 of the state’s 38 CDs, including three seats where the partisan lean calculation favored the Democrats. In addition to District 15, Trump also topped Kamala Harris in District 28 (Rep. Henry Cuellar; D-Laredo) and 34 (Rep. Vicente Gonzalez; D-McAllen). All of these CDs are located in South Texas.
Thus, the Trump performance largely destroys part of the Democrats’ racial gerrymander argument because he carried these three districts that have overwhelming minority populations.
In District 34, the Voting age minority population figure is 90.5 percent and 88.5 percent Hispanic. Trump won the district with a 51.8 – 47.4 percent majority. In District 15, the minority Voting Age Population (VAP) figure is 82.4 percent with the Hispanic VAP at 78.9 percent. President Trump carried this district with a strong 58.5 – 40.7 percent majority. District 28 has a minority VAP of 80.7 percent with a Hispanic VAP of 72.9 percent. The Trump winning margin here is 53.2 – 45.9 percent.
There are 19 Texas districts where White voters are the majority of the Voting Age Population. Trump won 18 of the 19. The one exception that supported Kamala Harris was Rep. Lloyd Doggett’s (D-Austin) 37th CD that stretches from Austin to San Antonio down the I-35 corridor.
Eighteen of the Texas congressional districts feature majority minority populations. Of those, Trump won nine of the 18 seats and exceeded the Republican benchmark in all 18. Trump also exceeded the DRA partisan lean GOP benchmark in the nine majority minority seats that Harris claimed. These statistics, to a significant degree, at least partially spoil the Democrats’ Voting Rights Act racial gerrymandering arguments.
Regarding the partisan lean figures from all of the Lone Star State’s 38 congressional districts, Trump exceeded the Republican benchmark in 32 of the seats. In the 14 districts where Democrats hold the partisan lean advantage, Trump exceeded the Republican benchmark in all.
In six districts, the Trump performance failed to reach the Republican benchmark, even though he carried each of the seats. Those where the President finished below the GOP partisan mean were TX-2 (Rep. Dan Crenshaw-R), TX-3 (Rep. Keith Self-R), TX-22 (Rep. Troy Nehls-R), TX-24 (Rep. Beth Van Duyne-R), TX-26 (Rep. Brandon Gill-R), and TX-38 (Rep. Wesley Hunt-R).
In Wisconsin’s eight congressional districts, we see similar patterns relating to President Trump’s performance in reference to the DRA partisan lean figures.
There, President Trump carried six of the state’s eight districts on his way to a 49.6 – 48.7 percent statewide victory. His vote total exceeded the DRA partisan lean in six of the eight districts. The only seats where he underperformed in relation to the Republican benchmark were in District 5 (Rep. Scott Fitzgerald-R), which ironically is the most Republican district in the state, and District 4 (Rep. Gwen Moore-D), Wisconsin’s most Democratic seat.
Though redistricting is designed to be done once per decade, changes in laws and procedures along with unending legal challenges to the district plans have made map drawing a perennial issue.
