John Cornyn, the longest-serving Republican in the Texas Senate race, faces a runoff battle against Texas Attorney General Ken Paxton. The contest tests former President Donald Trump's influence over the GOP primary process.
Cornyn, a three-term incumbent and Senate Republican whip, finished first in the primary but fell short of the 50 percent threshold needed to avoid a runoff. Paxton, backed by Trump, rallied conservative voters with an endorsement from the former president and positioned himself as the more Trump-aligned candidate in the race.
The runoff carries national implications for Republican control of the Senate. Trump has repeatedly endorsed Paxton, signaling his preference for a nominee closer to his political brand. Cornyn, while conservative, has occasionally broken ranks with Trump on legislative matters and represents the old guard of Texas Republican establishment politics.
Paxton's campaign centers on attacking the federal government and emphasizing border security, themes that resonate with Trump's base. He has criticized Cornyn for insufficient commitment to Trump's agenda. Cornyn counters that his seniority and legislative experience make him uniquely positioned to deliver for Texas and Republicans in the Senate.
The race reflects deeper divides within the Republican Party between Trump-endorsed candidates and establishment figures. In Texas, where Republicans dominate statewide elections, the GOP primary effectively determines the winner of the general election seat.
Cornyn's campaign emphasizes his record securing federal funding for Texas, his leadership role among Senate Republicans, and warnings that Paxton's nomination could energize Democrats. Paxton's team argues that only a Trump-backed alternative represents authentic conservative change.
The outcome will reveal whether Trump's endorsement proves decisive in a high-stakes primary, particularly against a well-funded incumbent with institutional support. A Paxton victory would demonstrate Trump's continued sway over Texas Republican voters. A Cornyn win would
