Ken Paxton Defeats John Cornyn in Texas Senate Primary

Texas just had one of the most dramatic political shake-ups in recent memory, and if you care about the balance of power in the U.S. Senate — which affects everything from healthcare to taxes to national security — this one's worth paying attention to.

Here's what happened: Ken Paxton, the controversial Texas Attorney General, just crushed four-term incumbent Senator John Cornyn in a Republican primary runoff. And it wasn't close. Paxton won with about 64 percent of the vote, while Cornyn received about 36 percent — a margin of roughly 28 percentage points. The loss makes Cornyn, first elected in 2002, the first-ever Republican senator from Texas to lose his party's nomination for re-election.

So who is Ken Paxton, and why does this matter? Paxton came to the race with serious legal and personal baggage. Since becoming a state official more than ten years ago, he's fended off criminal indictments, whistleblower allegations, and an impeachment by the Texas House — though he was ultimately acquitted in the Texas Senate. His estranged wife, state Sen. Angela Paxton, also filed for divorce last summer on "biblical grounds." Despite all that, his base loved him for it — they saw his battles as proof he's a fighter, not a pushover.

The key that unlocked Paxton's win? Trump. Polling and political analysts suggested the race was already tilting in Paxton's favor in recent weeks, and Trump's endorsement — which came while early voting was already underway — energized Paxton supporters and put Cornyn's bid for a fifth term on life support. Trump had called Paxton a "true MAGA warrior."

But what about Cornyn? He's no liberal — Cornyn repeatedly argued he's voted for Trump's agenda more than 99% of the time, but that's a message he wasn't able to get through to a majority of Republican primary voters. Paxton supporters argued Cornyn betrayed Republicans by working with Democrats on bipartisan gun legislation after the 2022 Uvalde school shooting. In MAGA world, that kind of compromise is a dealbreaker.

Now here's where it gets really interesting for November. With Paxton's win, the Senate seat in Texas became much more competitive than it would have been had Cornyn won. Cook Political Report moved the race from "Likely Republican" to "Lean Republican" just moments after the race was called. Paxton will face Democrat James Talarico, a state representative who won his primary outright months ago and has been sitting on a war chest while Republicans spent over $100 million beating each other up. Texas has long been a dream for Democrats, even though no Democrat has won statewide there since 1994. But this race might be the closest thing to a real shot they've had in a long time.
