In a stunning upset, former state Senator Ken Paxton has defeated incumbent Senator John Cornyn in the Texas Republican primary, becoming the first Texas GOP senator to lose a renomination contest. Paxton, who was endorsed by former President Donald Trump, rode a wave of conservative discontent to victory.
The win underscores the enduring influence of Trump in the Republican Party and signals a shift to the right in Texas politics. Paxton's campaign focused on immigration, border security, and cultural issues, while Cornyn was seen as more establishment-oriented.
Turnout was high, reflecting the intensity of the race. Paxton now advances to the general election, where he will face Democratic nominee Beto O'Rourke. The race is expected to be one of the most closely watched in the nation.
