Texas Primary Runoff: Senator John Cornyn Faces Crucial Test Against Trump-Backed Ken Paxton

AUSTIN, Texas — Voters across Texas are heading to the polls today as more than 40 primary runoff elections are set to be decided, headlined by a fierce, high-stakes battle for the future of the state's Republican party.

The marquee matchup features long-serving incumbent U.S. Senator John Cornyn fighting for his political survival against Texas Attorney General Ken Paxton. Following a long and bruising campaign, political observers view tonight's results as a critical litmus test for the Republican Party's identity in 2026, as well as a direct measure of how much sway President Donald Trump holds over his most loyal base.

Paxton enters election night in a strong position as the polling favorite, carrying significant momentum from a late-stage endorsement by President Trump. Though Trump waited months to officially wade into the primary race, he ultimately submitted his formal endorsement for Paxton on the first day of early voting. In his message to voters, Trump urged the MAGA base to turn out for the state's attorney general, praising Paxton's unwavering loyalty to his legislative priorities while heavily criticizing Senator Cornyn for failing to align with the movement.

The conventional wisdom among political insiders in Austin is that the race remains Paxton's to lose, largely due to the late surge provided by the White House endorsement. However, campaigns on both sides are bracing for a tense night as the final ballots are cast.

Polls are scheduled to close across Texas at 7:00 PM Central Time, at which point election officials will begin rolling out results that could reshape the state's political landscape for years to come.
