Texas Senate Showdown: Ken Paxton vs. John Cornyn Could Reshape the GOP

So here's the deal: Texas just wrapped up one of the most dramatic — and expensive — political fights in recent memory, and the outcome could ripple all the way to who controls the U.S. Senate this November.

On one side: John Cornyn, a 74-year-old four-term senator who's been a fixture of Texas Republican politics since 2002. On the other: Ken Paxton, the state's 63-year-old attorney general, a MAGA firebrand with a long and colorful trail of legal and personal controversies. Paxton beat incumbent Sen. John Cornyn in a runoff for the nomination, setting up a tough fight in November against Democratic nominee, state Rep. James Talarico.

This wasn't some low-key primary fight — the Texas race became the most expensive Senate primary in U.S. history, with both parties spending well over $100 million total. Think about that: more than $100 million just to decide who gets to run in November.

The whole thing started back in March when Cornyn, 74, and Paxton, 63, made it to Tuesday's runoff after each failed to garner a majority of votes in the state's March primary. Then came the twist that changed everything: President Trump endorsed Texas Attorney General Ken Paxton over incumbent Sen. John Cornyn in the Texas GOP runoff for U.S. Senate, one week before voting ended in the contentious and expensive primary. Polling and political analysts suggested the race was already tilting in Paxton's favor in recent weeks, and Trump's endorsement put Cornyn's bid for a fifth term on life support.

The bad blood between the two camps ran deep. Paxton's supporters said Cornyn betrayed the party by working with Democrats on bipartisan gun legislation after the 2022 school shooting in Uvalde, Texas. They also argued he should have helped nuke the Senate filibuster to clear the way for the Trump-backed SAVE Act to install new voting restrictions. Cornyn, for his part, told voters he voted with Trump more than 99% of the time — but that wasn't enough to satisfy the base.

So what does Paxton bring to the table besides Trump's blessing? Honestly, a lot of baggage. Paxton came to the race with legal and personal baggage. Since he became a state official more than ten years ago, he's fended off criminal indictments, whistleblower allegations and an impeachment by the Texas House. He was acquitted in the Texas Senate. His estranged wife, state Sen. Angela Paxton, filed for divorce last summer on "biblical grounds." His supporters? They don't see it that way — Paxton supporters say his ability to survive political upheaval shows he's a fighter.

Why does this matter to you, even if you don't live in Texas? Because Texas is a massive prize — Cornyn argued the primary exposed a crack in the red wall of Texas, which has remained a reliable and influential Republican state for decades. A Democrat has not been elected statewide there since 1994, and a Democrat hasn't represented Texas in the U.S. Senate since 1993. If Democrats can flip this seat — a longshot, but suddenly more realistic — it could flip the balance of power in the entire Senate. Democrats hope this seat — and the Senate majority more broadly — could be attainable thanks to the divisions among Republicans in this race.

Bottom line: Texas Republicans just picked a fighter over a sure thing. Whether that gamble pays off in November is a very open question.
