DALLAS (AP) — Texas Republican Sen. John Cornyn is trying to hold on for a fifth term in Tuesday’s GOP primary, while Democrats will choose whether to send Rep. Jasmine Crockett or state Rep. James Talarico to a November general election where the party once again hopes it has a chance.

Texas is one of three states kicking off this year’s midterm elections, a slate of primaries that come as the U.S. and Israel are at war with Iran. The war, which began over the weekend, has killed at least six U.S. service members, spiraled into a regional confrontation as Iran retaliated and sent oil and natural gas prices soaring. President Donald Trump, who campaigned on an isolationist “America First” agenda and went to war without authorization from Congress, faces mounting questions over its rationale and an exit strategy.

Tuesday also is the final day of voting in North Carolina and Arkansas in primaries that mark the start of the 2026 midterms, as Democrats look to break the GOP’s hold on Washington and derail Trump.

Cornyn faces a challenge from MAGA favorite Ken Paxton, the state’s attorney general, and Rep. Wesley Hunt in a contest that’s expected to advance to a May runoff between the top two vote-getters. The three Republicans have campaigned on their ties to Trump, who has not endorsed in the race.

Crockett and Talarico each argue that they are the stronger general election candidate in a state that backed Trump by almost 14 percentage points in 2024 and where a Democrat hasn’t won a statewide race in over 30 years.

Voters also are choosing House candidates using new congressional district boundaries that GOP lawmakers — urged on by Trump — redrew to help elect more Republicans.

Cornyn fights to hold seat, Crockett and Talarico race for Democrats

Cornyn hopes to avoid becoming the first Republican senator in Texas history not to be renominated.

His cool relationship with Trump is part of why Cornyn is vulnerable. He and allied groups have spent $64 million in television advertising alone since July to try stabilize his support.

Paxton began campaigning in earnest only last month but has made national headlines for filing lawsuits against Democratic initiatives. He has remained popular in Texas despite a 2023 impeachment trial on corruption charges, of which he was acquitted, and accusations of marital infidelity by his wife.

Senate GOP leaders, who are backing Cornyn, worry that Paxton’s liabilities would require the party to spend substantially to defend the seat if he is the nominee — money that could be better used elsewhere.

Paxton has run ads touting his support from Turning Point USA, the group founded by the late conservative activist Charlie Kirk, as well as Kirk’s praise for Paxton before he was assassinated in September.

Hunt’s entry into the race in October made it trickier for any primary candidate to win at least 50%, the threshold needed to avoid a May 26 runoff.

All three Republicans have run ads boasting of their coziness with Trump.

On the Democratic side, the party’s first major contest of 2026 offers a choice between stylistic opposites as it hungers for its first Senate win in Texas since 1988.

Talarico, a seminarian who often references the Bible, has held rallies across the state including in heavily Republican areas. Crockett, who has built a national profile for zinger attacks on Republicans, has focused on turning out Black voters in the Dallas and Houston areas.

Talarico had outspent Crockett on television advertising by more than four to one as of late February. He got a burst of attention last month from CBS’ decision not to air his interview with late-night host Stephen Colbert. Colbert said the network pulled the interview for fear of running afoul of Trump’s FCC. Talarico’s campaign announced it raised $2.5 million in the 24 hours after the interview — which was streamed online — was pulled from TV.

Key House primaries

Texas Republicans’ unusual, mid-decade redistricting was aimed at helping Trump’s party pick up five Democratic-held seats in an effort to avoid losing control of the House. It set up some intraparty conflicts between Democratic incumbents, and what are expected to be some of November’s most competitive races.

In the 34th District, former Rep. Mayra Flores is attempting a comeback. Flores made history in a 2022 special election as the first Republican to win in the Rio Grande Valley in 150 years, but she lost her bid for a full term later that year. She faces Eric Flores, a lawyer endorsed by Trump, for the nomination to run against Democratic Rep. Vicente Gonzalez.

In the 23rd District, Rep. Tony Gonzales is considered vulnerable after fellow Republicans called on him to resign over an affair with a staffer who killed herself. He is being challenged by gun manufacturer and YouTube influencer Brandon Herrera, who calls himself “the AK guy.” The district includes Uvalde, site of a deadly 2022 shooting at Robb Elementary School.

Republican Rep. Dan Crenshaw is challenged in the 2nd District by GOP state Rep. Steve Toth, who was endorsed by Sen. Ted Cruz.

Former Major League Baseball star Mark Teixeira is running in District 21, in southwest Texas, for the seat held by Republican Rep. Chip Roy, who is running for state attorney general. Teixeira, a Republican, played for four MLB teams, including the Texas Rangers and the New York Yankees when they won the 2009 World Series.

Democrat Bobby Pulido, a Latin Grammy winner, is running in South Texas’ 15th District against physician Ada Cuellar. The nominee will face two-term Republican Rep. Monica De La Cruz.

In the 33rd District, Democratic Rep. Julie Johnson faces former Rep. Colin Allred, a former NFL linebacker and 2024 Senate nominee. Johnson, a first-term congresswoman, is seen as vulnerable partly because Allred previously represented part of the district, which weaves through the Dallas and Fort Worth areas. He also retains a national fundraising network from his Senate campaign.

And Democratic Rep. Al Green also is fighting to stay in office after his Houston-based 9th District was drawn to be lean Republican. Green, 78, is now running in a newly drawn 18th District against Democratic Rep. Christian Menefee, 37, who won a January special election for the current 18th District. The new one includes two-thirds of Green’s old district.

Abbott and Hinojosa seem bound to face off for governor, while Roy seeks Paxton’s office

Republican Gov. Greg Abbott is running for reelection and faces a likely matchup with Democratic state Rep. Gina Hinojosa.

Four-term U.S. Rep. Chip Roy is seeking the GOP nomination for state attorney general, with Paxton running for Senate. Roy has been a prominent member of the conservative Freedom Caucus.
