Most of the Republicans that emerge from the GOP primaries in North Carolina today will be men. But in the 1st District, Democratic Rep. Don Davis awaits today's outcome, which will determine if he'll face Republican MAGA-firebrand, Sandy Smith (again), or wealthy businesswoman, Laurie Buckhout. As we wrote earlier, the 1st District will likely be the state's sole competitive House race in November.

In the first 19 towns in Vermont with reasonably complete results, Trump's support this year correlates at around 0.60 with his support back in 2016, which is a pretty high correlation and similar to what we saw in New Hampshire. But as we've observed in other states, Trump is also doing well in the Vermont towns where Ted Cruz had more support in 2016. Since 2016, Trump has consolidated the GOP's right-leaning voters.

We're still waiting on results in most races, but I'm also watching Oklahoma, where polls have just closed. Trump has a massive lead against Haley in recent Republican primary polling in Oklahoma, and, since the primary is closed, Haley can't count on independents and Democrats shrinking his margin against her. Trump won the state in the 2020 general election with 65 percent of the vote, making it one of his best states in the U.S., and Biden did not win a single county there.

Heavily evangelical, with a mix of Southern and Western spirit, Oklahoma remains one of the reddest states in the country. Whoever wins this primary race is almost certain to carry the state in November. Sen. Markwayne Mullin, the state's junior senator, has called on Haley to drop out if she doesn't win a single state tonight.

The 2024 primary season has been weirder than I think anyone expected. The two parties feel like they have a lot of internal tension, but with a current and a former president seeking their parties' respective nominations, it hasn't been very competitive. One result of this has been that we've been looking for clues to the general — the Trump-Biden rematch — in the primary results. In turn, this has meant some overinterpretation of primary results — it's not a given that people who cast a vote for another candidate won't come home in the general.

It's also hard to compare the internal dynamics of the two parties and apply those to predictions for the general. Dean Phillips' candidacy, for example, has presented himself as a moderate, pragmatic alternative to Biden — but he's mostly emphasized the age difference. Some Democrats have been unhappy with the policies of the administration, especially on the Israel issue, but there hasn't been a progressive candidate to challenge him. Trump, on the other hand, has faced — and beaten — experienced opponents with more substantive disagreements. This makes it harder to use the primary as a direct roadmap to what the candidates' liabilities might be in the fall.

Sitting governors and attorneys general don't usually openly try to defeat incumbents of their own party, but Texas Gov. Greg Abbott and Attorney General Ken Paxton are just built different, I guess. Today's Texas primaries are the culmination of two separate intraparty power struggles from the past year, in which Abbott and Paxton are actively trying to defeat Republicans who have defied them in the state legislature.

In May 2023, the Texas state House impeached Paxton on charges of bribery and abuse of office. He was later acquitted by the state Senate, but he has embarked on a revenge tour against those who supported his impeachment by endorsing primary challengers to 35 incumbent Republicans.

Meanwhile, Abbott suffered a massive political defeat last year when a group of mostly rural Republican legislators blocked his top priority, a school voucher program. In what the Houston Chronicle has called a "legacy-defining" campaign, Abbott has spent more than $4 million trying to oust 10 anti-voucher Republicans running for reelection.

Even Trump has gotten in on the act: He has endorsed at least eight primary challengers to sitting representatives, all of whom either voted against vouchers or voted to impeach Paxton (who is a close Trump ally).

If Paxton, Abbott and Trump are successful, the Republican caucus in the Texas state House will look very different — and further right — next year. Throughout the night, I'll be watching for how many incumbents they successfully topple.
