And now ABC also projects that Haley will win Vermont. The race remains super close, however, and it’s not yet clear how delegates will be awarded.

Polls have now closed in California, where all parties run on a single primary ballot (other than in presidential races). Unfortunately, neither party is particularly popular in the state. According to a February survey from the Public Policy Institute of California, likely primary voters in California don’t have a favorable view of either political party: The Democratic party is underwater by 10 percentage points, with 44 percent of likely voters saying they have a favorable impression of the party and 54 percent saying they have an unfavorable view. The Republican party fares even worse, with a net favorability of -55 points, 22 percent favorable and 77 percent unfavorable.

The New York Times and the Associated Press have projected that Haley will win the Republican primary in Vermont, making it the second win for her after Washington, D.C. (ABC News has not yet made a projection in this race.)

While Trump remains ahead on the delegate count, the win could give some juice to her campaign. She's vowed to stay in because she says that Trump and Biden are both too old and out of touch, and she has been capturing a sizable minority of primary voters who are unhappy with the former president in many states across the country. Still, she'll need to get a majority of the final vote to take all of the delegates, and that remains up in the air. With 92 percent of the expected vote in, she has 49.7 percent to Trump's 46 percent. If neither candidate reaches 50.1 percent, they'll split the state's delegates.

North Carolina’s 13th District is yet another Democratic-held seat that North Carolina Republicans redrew this year to be safely red. Unsurprisingly, the GOP primary attracted a wide field, and with 67 percent of the expected vote counted according to the Associated Press, attorney Kelly Daughtry is in first place with 29 percent, followed by former federal prosecutor Brad Knott with 18 percent, businessman DeVan Barbour with 17 percent and yet another businessman Fred Von Canon with 16 percent. As a reminder, if no one gets 30 percent, the runner-up is entitled to request a runoff.

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.
