A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election. Texas utilizes an open primary system. State law requires voters to sign the following pledge before voting in a primary: "I am a (insert appropriate political party) and understand that I am ineligible to vote or participate in another political party's primary election or convention during this voting year."[1]

Post-filing deadline analysis
The following analysis covers all U.S. House districts up for election in Texas in 2026. Information below was calculated on Dec. 8, 2025, and may differ from information shown in the table above due to candidate replacements and withdrawals after that time.
Two hundred fifty-two candidates — 98 Democrats and 154 Republicans — ran for Texas’ 38 U.S. House districts. That’s 6.6 candidates per district. There were 4.2 candidates per district in 2024, 5.8 in 2022, 6.4 in 2020, 5.9 in 2018, 3.5 in 2016, and 2.8 in 2014.
These were the first elections to take place since the Texas Legislature passed a new congressional map. The Texas House of Representatives passed it on Aug. 20, 2025, and the Texas Senate passed it on Aug. 23, 2025. Texas Gov. Greg Abbott (R) signed the new congressional map into law on Aug. 29, 2025.
This was the highest total number of candidates who ran for the U.S. House since 2014.
Ten districts were open in 2026. There were three districts open in 2024, six in 2022, six in 2020, eight in 2018, two in 2016, and one in 2014.
Reps. Morgan Luttrell (R-8th), Michael McCaul (R-10th), Jodey Arrington (R-19th), Troy Nehls (R-22nd), Marc Veasey (D-33rd), and Lloyd Doggett (D-37th) retired from public office. Reps. Jasmine Crockett (D-30th) and Wesley Hunt (R-38th) ran for the U.S. Senate. Rep. Chip Roy (R-21st) ran for attorney general of Texas.
Two incumbents — Reps. Christian Menefee (D) and Al Green (D) — ran against each other in the redrawn 18th district. Menefee was the incumbent in the 18th district, and Green was the incumbent in the 9th district.
Fifty-nine primaries — 32 Democratic and 28 Republican — were contested in 2026. In total, there were 39 contested primaries in 2024, 44 in 2022, 50 in 2020, 46 in 2018, 33 in 2016, and 19 in 2014.
Fifteen candidates ran for the open 9th district, 21st district, and 35th district, tying for the most candidates running for a district in 2026.
Nineteen incumbents — eight Democrats and 11 Republicans — faced primary challengers in 2026. There were 19 incumbents in a contested primary in 2024, 19 in 2022, 18 in 2020, 15 in 2018, 19 in 2016, and 12 in 2014.
Candidates filed to run in the Republican and Democratic primaries in all 38 districts, meaning no districts were guaranteed to either party.Partisan Voter Index
