No surprises so far in the Tar Heel state tonight: ABC News projects Trump will win the GOP primary and Biden will win the Democratic primary. I can also report that ABC News has projected Lt. Gov. Mark Robinson has won the Republican primary for governor.

There are a handful of particularly hot downballot contests in North Carolina worth paying attention to tonight. You can read about them in more detail in my preview from last week, but here's a quick recap to get you up to speed.

Neither the Democratic nor Republican primary for governor is competitive, but they're worth paying attention to because this race will be competitive come November. If Republican front-runner Lt. Gov. Mark Robinson — a deeply conservative Christian and controversial figure — wins the nomination and defeats Attorney General Josh Stein, who is leading the Democratic race, it would give Republicans a governing trifecta in the state for the first time in eight years.

Thanks to redistricting, North Carolina's 1st Congressional District is expected to be the state's only competitive congressional race this fall. Incumbent Democratic Rep. Don Davis will be squaring off against one of two Republicans: Jan. 6-attending, MAGA firebrand Sandy Smith and retired U.S. Army Colonel Laurie Buckhout, a wealthy businesswoman who has spent more than $1 million of her own money boosting her campaign.

Then there are four safely Republican open seats elsewhere in the state, where the GOP primary will effectively decide the next representative. In the 6th District, the six-candidate field includes Bo Hines, a former wide receiver for North Carolina State University who ran unsuccessfully in 2022. In the 8th District outside Charlotte, the two GOP front runners are state Rep. John Bradford, who has poured $1.3 million of his own money into his campaign, and Baptist minister Mark Harris, whose 2018 congressional win was thrown out due to allegations of ballot fraud.

In the 10th District, state Rep. Grey Mills is hoping to upset front-runner Pat Harrigan, a gun manufacturer who was the Republican nominee in the 14th District in 2022. And in the 13th District, there are no fewer than 14 candidates running — this one looks like a jump ball and may even go to a May 14 runoff if none of the candidates can clear 30 percent of the vote.

I'll have more on these races and more from the Tar Heel State soon! Polls close at 7:30 p.m. Eastern.

As I mentioned earlier, 2018 was a watershed year for political ambition among Democratic women. Not only did Democratic women run in record numbers in 2018, they also outperformed Democratic men in their primaries. And in November of that cycle, female candidates were responsible for more than 60 percent of the congressional seats that flipped from red to blue. That year was a nail in the "women aren't electable" coffin.

There are a few Democratic women running tonight who are vying to do just that once again.

In southern California's 40th District, which spans parts of Orange, Riverside and San Bernardino counties, engineer Allyson Muñiz Damikolas is hoping to face Republican incumbent Young Kim in November. Kim herself was one of the few Republican women who won in 2020 when she flipped California's 39th District by less than 5,000 votes Due to redistricting, Kim ran in the 40th District in 2022, where she won by a much larger margin. Still, this region of California is in flux demographically and politically, so it makes sense as a target for Democrats. EMILY's List is backing Muñiz Damikolas, but to advance to November, she'll need to get past fellow Democrat, retired fire Capt. Joe Kerr, first, who has been endorsed by the Congressional Progressive Caucus PAC.

Next, in Texas's 15th District, small business owner Michelle Vallejo is favored to advance tonight to a rematch against Republican incumbent Rep. Monica De La Cruz. Vallejo, who has endorsements from EMILY's List and the DCCC, lost by nearly nine percentage points in 2022, but Democratic groups have invested more in the race this time around as a top pickup opportunity. And in California's 3rd District, wildfire specialist Jessica Morse is running to face the Republican incumbent, Rep. Kevin Kiley. Morse is endorsed by EMILY's List, but not the DCCC. She and Kiley are likely to advance out of today's top-two primary, which includes a third-party candidate.

In addition to these, there are several bluer districts with incumbent-less primaries today where Democratic women will be competitive:

- Rep. Colin Allred is running for Senate, opening his seat in Texas's 32nd District. State Rep. Julie Johnson has support from EMILY's List and seems to be one of the top two candidates in a crowded Democratic primary.

- Rep. Tony Cárdenas announced his retirement in his blue San Fernando Valley district (California's 29th). Luz Maria Rivas, who has support from EMILY's List and the Congressional Progressive Caucus PAC, should finish in the top two today.

- Rep. Barbara Lee isn't running for reelection in California's 12th District, instead vying for the Senate. Organizer and civil rights activist Lateefah Simon is a clear front-runner. She has Lee's endorsement, as well as Gov. Newsom's, and backing from EMILY's List.

- Rep. Anna Eshoo announced her retirement after three decades in Congress, opening up California's 16th District. EMILY's List is backing former Stanford dean Julie Lythcott-Haims, but she's caught in a tight race with four other strong candidates who have her beat on the spending front.

- Rep. Katie Porter is also running for Senate instead of reelection in California's 47th District. Lawyer Joanna Weiss, who has an endorsement from EMILY's List, looks to be in a contentious race with state Sen. Dave Min to become the Democratic flagbearer this fall.

Given that Lee, Eshoo and Porter are women and not all of today's female candidates are favored to advance, today's races mainly give Democratic women a chance to maintain the progress they've made in recent cycles.

As Geoffrey said, polls just closed in our two big Eastern states tonight, Vermont and Virginia. Tonight, I'll be keeping an eye on Vermont early. Vermont is much like its neighbor, New Hampshire, in that it has the demographics that ought to be favorable to Haley. It's one of the least religious states in the country and has a high rate of college attainment. Moreover, Haley has the backing of the Republican establishment in the state. The primary is open, meaning that independents and Democrats could cross the aisle to vote for her, and her campaign has visited the state recently, hoping to drum up support. But she's still earning only about a third of the vote in recent polling, and odds are she'll be disappointed there. Since it's a winner-take-all state, she could walk away with none of its 17 delegates. As Nathaniel wrote after the first-in-the-nation primary in New Hampshire, if Haley couldn't win there, she probably won't win anywhere.

In several of California's open congressional districts, tonight could be the end of any suspense about who the next representative will be. Or, it could be the start of an eight-month intraparty slog.

That's because California's unique all-party primary system — where the top two primary vote-getters advance to the general election — allows for either a traditional contest between a Democrat and a Republican or a fight between members of the same party in the general election, and it's not always obvious which one you're going to get. That's the case in at least four open-seat races today — three Democratic and one Republican.

In California's 16th District, there are nine Democrats but just two Republicans vying to replace Democratic Rep. Anna Eshoo. While limited polling of the district suggests that former San Jose Mayor Sam Liccardo or Santa Clara Supervisor Joe Simitian, both Democrats, are the front-runners, if one of the two Republicans consolidates most of the GOP vote and the Democratic vote scatters among the many candidates, a Republican could finish in the top two. In the 2022 primary, the Republican candidates didn't meet that threshold, splitting a combined 22 percent of the vote; the four GOP candidates in the state's Senate race won a combined 24 percent in the district. A Republican advancing would ensure that whichever Democrat also finished ahead would win the general election in November, given the district's partisan bent. But if two Democrats finish in the top two, it'll be a real race.

Same goes in the 30th District, where Adam Schiff is leaving to run for Senate. Twelve Democrats and just two Republicans will appear on the ballot there. In the 2022 primary, four GOP House candidates totaled 21 percent, and Senate GOP candidates combined for a smaller 22 percent. Democratic state legislators Anthony Portantino and Laura Friedman, and Democratic former city attorney Mike Feuer are the front-runners for this seat; if two of those three make it to the general election, it will be an expensive and sharp-elbowed race to November, but if one of the Republicans squeezes in, it's basically over.

In the 31st District, where Democrat Grace Napolitano is retiring, six Democrats and two Republicans are running. In 2022, the one Republican running for the seat, Daniel Martinez, advanced to the general by winning 37 percent of the vote in the primary. Former Rep. Gil Cisneros, state Sens. Susan Rubio and Bob Archuleta, former Monrovia Mayor Mary Ann Lutz and attorney Greg Hafif are all running well-funded Democratic campaigns, creating the possibility that Martinez, who is running again, could finish in the top two instead of two Democrats, effectively ending this race tonight.

And in Kevin McCarthy's old seat, the 20th District, it's a similar story with the parties reversed. There, the two Democrats will probably combine for around 30 percent of the primary vote (in 2022, the House candidates combined for 30 percent and the Senate candidates for 32 percent), while six Republicans fight over the remaining 70 percent (a seventh dropped out but remains on the ballot).
