John Cornyn spent $70 million telling Texas he loves Donald Trump.
Ken Paxton handed him one bill and asked him to prove it.
What Cornyn said next — after 24 years of promises — exposed him in a way money couldn't cover.
Cornyn Refuses to Kill the Filibuster to Pass the SAVE America Act
Neither RINO Senator John Cornyn nor Texas Attorney General Ken Paxton broke 50% in the March 3 primary, sending both to a May 26 runoff. Cornyn led by less than one point despite outspending Paxton 15-to-1.
Days later, Paxton posted a public offer: pass the SAVE America Act by forcing a talking filibuster, and he walks away from the race.
The SAVE America Act requires proof of citizenship to register to vote and photo ID at the polls. Trump called it "more important than everything else we're working on other than the war."
Every Senate Democrat opposes it. The only thing standing between the bill and Trump's desk is the 60-vote filibuster threshold.
Republicans have enough votes to force a talking filibuster — requiring Democrats to physically hold the Senate floor to block it — but only if senators like Cornyn get behind it.
Cornyn's initial response was a study in evasion.
"I repeat what I have consistently said: I support the bill and have encouraged Senate Republicans to get it done."
He never mentioned the filibuster. Paxton called him a coward. Then something remarkable happened.
Forty-eight hours later, Cornyn reversed course — announcing on March 7 that he would support the talking filibuster after all. Paxton's verdict: "I made Cornyn more conservative in the last 3 days than he's been in the last 24 years."
The Lone Star Liberty PAC wasn't buying it. Just days before his reversal, Cornyn had said the talking filibuster wasn't "feasible" and the "process could go on for literally weeks, if not months, and still not be successful."
Now, with a runoff on the line and Trump watching, he's suddenly on board. That's not conviction. That's a man checking which way the wind is blowing.
John Cornyn's Senate Record: Jack Smith, Lisa Monaco and a Vote Against Trump
Twenty-four years of votes don't lie.
When the House moved to investigate Alvin Bragg's lawfare against Trump, Cornyn told Republicans to drop it — urging them to "stick to the agenda they ran on."
Jack Smith came after the president. Cornyn said nothing.
Biden nominated Lisa Monaco — a Mueller protégé — to run the DOJ as No. 2. Cornyn voted to confirm her.
In May 2023, Cornyn told anyone who would listen that Trump couldn't win a general election and that Republicans needed someone else.
On video, he called Fauci a national treasure. Trump's border wall, he said, was naïve.
Then he wrote a gun control bill with Democrats, whipped the Republican votes to pass it, and stood by while Biden thanked him by name at a White House celebration. Texas Republicans booed him at the state GOP convention. He spent $70 million hoping voters forgot all of it.
The same man Jasmine Crockett called her "best partner in the Senate" is asking Texas conservatives for six more years.
The Texas Senate Runoff and the Trump Endorsement That Changes Everything
Donald Trump hasn't endorsed yet — and that silence is the story.
Trump advisers told The Atlantic this week they expect an endorsement of Cornyn, citing his better-than-expected primary finish.
Senate Majority Leader John Thune and the party establishment have been lobbying the White House hard for weeks, arguing Cornyn is the safer general election bet against Democrat James Talarico.
Trump said that he wouldn’t endorse in Texas until the SAVE America Act landed on his desk.
Paxton's gambit reframed the entire race.
In 72 hours, he forced a 24-year incumbent senator to reverse his position on one of Trump's top priorities — without a single vote being cast.
The runoff electorate is smaller and more conservative. The voters who show up the day after Memorial Day are Paxton's base.
Cornyn won the primary by burning through the better part of $100 million, by Paxton's own accounting, to finish one point ahead.
He doesn't have another $100 million.
And now every Republican voter in Texas knows exactly what it takes to make John Cornyn change his mind: pressure, a primary threat, and 48 hours.
