Republicans are already picking through the wreckage of Tuesday’s losses, with plenty of Monday morning quarterbacking about what went wrong. The party lost the U.S. House, the U.S. Senate, and Texas, leaving conservatives searching for answers after a brutal night.

Iran, gas prices, and weak Republican turnout are among the explanations being tossed around. Outgoing Sen. John Cornyn of Texas, however, decided he had the answer, despite his own recent rejection by Republican primary voters.

Cornyn blamed the defeat on Republicans forgetting what he called the basic rules of coalition politics. He pointed to the party’s losses in Congress and in his home state, which he described as a conservative cornerstone for more than three decades.

His four rules were “Add, don’t subtract,” “Be likeable,” “Do what you promised,” and “Character & integrity still matter.” Cornyn closed his message with, “Time to turn the page and rebuild.”

Last night, Republicans lost the U.S. House, the U.S. Senate, and my home state of Texas, a conservative cornerstone for more than three decades, because our party forgot the basic rules of coalition politics:

Trump's Sovereign Wealth Fund: What Could It Mean For Your Money?

That sermon landed with a thud because Cornyn had just lost his own primary to Ken Paxton by almost 28 points. Nearly $100 million was spent on the contest, yet Cornyn still suffered a lopsided defeat.

The criticism practically writes itself. Cornyn was lecturing Republicans about winning after voters concluded that he had failed to satisfy the very standards he was now promoting as essential.

.@JohnCornyn let's apply your logic to, I don't know, .............You.

1. Add, don’t subtract: You subtracted the mandate of your constituents when you did absolutely nothing to fight for the SAVE Act, when you compromised on 2A rights at the request of @SenMcConnell , and you were open to some amnesty for those who entered our country illegally. 2. Be likeable: You were never liked by your constituents. Which is why the "bad person" as you described @KenPaxtonTX soundly beat you by 30+ points. Even then you were tone deaf to the message they sent to you. 3. Do what you promised: The only thing you promised was more of the same. The same was not what the voters wanted. 4. Character & integrity still matter: Both of which you lacked demonstrated by how you acted after your loss. You immediately began undermining Paxton. Luckily, a year from now, people will see you in public and not remember who you were. Enjoy your well earned anonymity. — Chris Hinkle (@TheChrisHinkle) November 4, 2026

Republican primary voters had already delivered their judgment. They did not believe Cornyn was addressing their concerns, and they rejected him before he ever reached the general election ballot.

Paxton ultimately lost the general election, but the losses stretched far beyond him. Texas Gov. Greg Abbott was also voted out, while other Republicans fell during the blue wave that swept the state.

Democrat James Talarico received 5.4 million votes, while Paxton received 4.2 million. That was the same vote total Sen. Ted Cruz of Texas received in 2018.

Cornyn likely would have lost as well had he reached the general election. His primary defeat had already shown that voters were deeply unhappy with him, making his confidence in diagnosing everyone else’s failures especially rich.

After losing the primary, Cornyn said he would support the Republican ticket. Yet during the following months, he repeatedly took shots at Paxton through passive aggressive tweets and comments instead of rallying behind the nominee selected by voters.

That conduct hardly matched Cornyn’s own warning against subtraction. At the moment when he could have supported the nominee, he instead continued running Paxton down, directly undercutting the political rulebook he later presented to Republicans.

Cornyn then moved quickly to congratulate Talarico after the Democrat won. Coming after months of criticism aimed at Paxton, the congratulations only sharpened the portrayal of Cornyn as bitter toward the candidate who defeated him.

Now Cornyn apparently believes he can remain relevant and help with the rebuilding process. The verdict is considerably harsher, arguing that he is kidding himself and is politically finished in Texas.

The broader concern is that Cornyn and Republicans like him may have helped damage the party’s standing in Texas for some time. After such sweeping losses, a politician rejected by his own primary voters is hardly the most convincing person to deliver a lecture on coalition building, character, or victory.
