Redistricting

2025-2026

See also: Redistricting in Texas ahead of the 2026 elections

In August 2025, the Texas Legislature proposed a new congressional district map during special legislative sessions that prompted Democratic legislators to leave the state to prevent a quorum.[15][16] Click here to read more about the 2025 Democratic walkout during mid-decade redistricting in Texas.

On August 20, 2025, the Texas House approved House Bill 4 containing a new congressional map by an 88-52 vote along party lines.[17] On August 23, 2025, the Texas Senate approved the map by an 18-11 vote along party lines.[18] Texas Gov. Greg Abbott (R) signed the new map into law on August 29, 2025.[19] The bill text stated the new district boundaries would take effect for the 2026 elections.[20]

On November 18, 2025, a three-judge panel ruled 2-1 to block Texas from using the 2025 map in the 2026 elections, and ordered the state to use the 2021 map.[21] On November 21, 2025, the U.S. Supreme Court temporarily paused the panel's ruling, reinstating the new map pending further Court action.[22] On December 4, 2025, the U.S. Supreme Court ruled the 2025 map could be used for the 2026 elections.[23]

2020-2021

See also: Redistricting in Texas after the 2020 census

After the 2020 census, Texas enacted new congressional districts on October 25, 2021. The Senate released a proposed congressional map on September 27, 2021, and approved an amended version of the proposal on October 8, 2021.[24] On October 13, 2021, the House Redistricting Committee approved an amended version of the congressional map, and both chambers of the legislature approved a finalized version of the map on October 18, 2021. The Senate approved the proposal in an 18-13 vote, and the House approved the bill in an 84-59 vote.[25] Gov. Greg Abbott (R) signed the map into law on October 25, 2021.[26] This map took effect for Texas' 2022 congressional elections.

How does redistricting in Texas work? In Texas, both congressional and state legislative district boundaries are drawn by the Texas State Legislature. These lines are subject to veto by the governor.[27]

If the state legislature is unable to approve a state legislative redistricting plan, a backup commission must draw the lines (the backup commission is not involved in congressional redistricting). This backup commission, established in 1948, comprises the following members:[27]

  1. Lieutenant governor
  2. Speaker of the Texas House of Representatives
  3. Attorney general
  4. State comptroller
  5. Commissioner of the General Land Office

The Texas Constitution requires that state legislative districts be contiguous and "that they preserve whole counties when population mandates permit."[27]

Following the 2010 United States Census, Texas gained four congressional seats. Texas' final congressional redistricting plan was approved by the Texas Legislature and signed by Gov. Rick Perry (R) in June 2013.[28][29][30]

This made Texas' 13th the 9th most Republican district nationally.[32]

Daily Kos calculated what the results of the 2020 presidential election in this district would have been following redistricting. Donald Trump (R) would have defeated Joe Biden (D) 72.0%-26.5%.[33]

2022

Heading into the 2022 elections, based on results from the 2020 and 2016 presidential elections, the Cook Partisan Voter Index for this district was R+26.

Daily Kos calculated what the results of the 2020 presidential election in this district would have been following redistricting. Joe Biden (D) would have received 26.5% of the vote in this district and Donald Trump (R) would have received 72.0%.[35]

2018

Heading into the 2018 elections, based on results from the 2016 and 2012 presidential elections, the Cook Partisan Voter Index for this district was R+33. This meant that in those two presidential elections, this district's results were 33 percentage points more Republican than the national average. This made Texas' 13th Congressional District the most Republican nationally.[36]

FiveThirtyEight's September 2018 elasticity score for states and congressional districts measured "how sensitive it is to changes in the national political environment." This district's elasticity score was 1.01. This means that for every 1 point the national political mood moved toward a party, the district was expected to move 1.01 points toward that party.[37]
