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.

The biggest downballot race in California is its U.S. Senate contest. Although 27 candidates filed for the race to fill the seat of the late Democratic Sen. Dianne Feinstein — who died last fall — the four leading contenders are Democratic Reps. Adam Schiff, Katie Porter and Barbara Lee, plus Republican Steve Garvey, a former Major League Baseball player. The front-runner appears to be Schiff, who is polling at around 25 percent in 538's California primary polling average. This puts him just a bit ahead of Garvey and Porter, who are right around 20 percent for the coveted second spot. Behind them is Lee, who is polling just under 10 percent.

The race has largely centered on Schiff and Porter, both of whom are fundraising powerhouses. As of Feb. 14, Schiff had brought in $29.8 million in net contributions, while Porter had collected $16.7 million, putting them each well ahead of Lee ($4.8 million) and Garvey ($2.1 million). The two leading Democrats also brought over huge sums left over from their House accounts — $21 million for Schiff and $7.4 million for Porter.

In the final weeks, Schiff has tried to use his massive campaign war chest to push Garvey into second place. Schiff has run ads that attack Garvey for his conservative views and past support for Trump, but the spots intend to raise Garvey's profile among Republican voters. By doing that, Schiff could help Garvey consolidate the GOP vote and finish ahead of Porter, relieving Schiff of a demanding general election campaign against the fellow Democrat. A pro-cryptocurrency super PAC may also help Schiff out, after swooping in with $10 million in outside spending seeking to derail Porter.
