Ken Paxton and John Cornyn face off in Texas’s Republican Senate runoff on Tuesday, a contest that will decide who takes on Democrat James Talarico in November. The winner will enter the general election with the backing of a party that is still deciding whether it wants a hard-right firebrand or a veteran operator who has spent years inside the machinery of Texas Republican politics.
Donald Trump endorsed Paxton last week, calling him “a true Maga warrior,” a nod that could help the state attorney general turn a bruising month into a comeback. Cornyn, a four-term incumbent, narrowly beat Paxton in a primary on 3 March and now has to defend a seat against a challenger who is carrying Trump’s approval and the anger of the party’s activist base.
The race matters now because Tuesday is the last step before November, when the runoff winner will meet Talarico, a state legislator whose groundswell of popularity has already made Democrats think the seat may be more open than it first appeared. A Paxton victory would extend Trump’s winning streak of endorsements, but it would also give Republicans a candidate whose impeachment and indictment make the Senate race more difficult to control.
Cornyn is not a stranger to Texas politics. He is a former Texas attorney general and state supreme court justice who has helped the party raise millions of dollars and worked with Democrats on bipartisan bills, including a gun safety measure he helped negotiate in 2022. His style fits an older version of the state party, one shaped by the Bush family’s pragmatic, business-friendly Republicanism rather than the combative politics that now drive much of the base.
That gap in style may matter more than the policy differences. Cornyn and Paxton would vote the same way on almost every piece of legislation, which is why the runoff has become as much about vibe as ideology. As one Republican voter, Jim Tubbesing, put it, Paxton is “more conservative.” He added: “He has been good for Texas. I vote for the policy, not the fact that he’s alleged to have done something.” Tubbesing also dismissed Cornyn as a “Rino: Republican in name only.”
The tension for Republicans is simple. Paxton’s name carries loyalty with the party’s most fervent voters, but it also carries legal baggage and the risk of turning a winnable seat into a liability. Cornyn’s backers see him as a calmer, steadier choice, the kind of “calm, serious, problem-oriented politician” described by political scientist Cal Jillson. They argue he is better suited to a state where Republicans have long preferred discipline over drama.
That argument is no longer just academic. Texas was historically shaped by the Bush family’s pragmatic, business-friendly style, and Cornyn has been one of the last major figures from that tradition. Jon Taylor said he is “like the last of the old-guard Republicans in this state, someone who could – in some respects – trace his lineage back to both George Herbert Walker Bush and George W Bush.”
Democrats are watching for a different reason. Cristina Tzintzún Ramirez said: “It’s one of the most exciting races in the country and, if Ken Paxton becomes the candidate, Talarico has a shot.” Talarico is trying to become the first Democrat in more than 30 years to win statewide office in Texas, and a Paxton nomination would give him the kind of opening Democrats have searched for without finding it in decades.
For now, the question has been narrowed to one ballot and one state. If Cornyn wins, Republicans keep a familiar hand and a safer general-election path. If Paxton wins, Trump gets another endorsement victory — and Texas Republicans may have chosen a fight they can win only if the state’s political ground shifts beneath them.
