Analysis
Primary upset
Texas Attorney General Ken Paxton easily beat Senator John Cornyn in the Republican runoff for the US Senate, delivering a sharp defeat to a veteran incumbent who had served in Congress for 23 years. The result had been expected for weeks, but it still stands out because Cornyn was a senior Senate Republican leader and a familiar figure in Washington.
What happened
The BBC says the contest became the most expensive Senate primary campaign in US history. Paxton, 62, was backed by Trump's populist base in Texas and attacked Cornyn as too old, too cautious, too close to the political establishment, and disconnected from Texas conservatives. Cornyn had the advantage in fundraising and party standing, but Trump ultimately endorsed Paxton after it looked increasingly likely that the attorney general would win.
Bigger picture
Paxton now moves on to face Democratic state legislator James Talarico in November. Democrats see Paxton as the weaker candidate and hope the matchup gives them a chance to flip a Senate seat in a state that has not elected a Democrat to the chamber since 1988. The race will help decide whether Democrats can regain control of the Senate for the last two years of Trump's presidency.
The article frames Paxton's win as another example of Trump's endorsement power, but also as evidence that the Republican base in Texas may be driven by forces larger than Trump himself. The same night also saw Republican primary wins by Trump-backed candidates in other Texas races, underlining the reach of the former president's influence in the state.
