Turning back to the high-stakes GOP primary in Alabama's 1st District, Moore leads Carl 55 percent to 45 percent, with 87 percent of the expected vote reporting. This undoubtedly makes Moore a favorite to win, but it's not over just yet. That's because 90 percent of the expected remaining votes are in Mobile County, Carl's home base. So far, Carl has carried Mobile 72 percent to 28 percent. That's been extremely helpful to him, but he'll need to win the remaining votes by an even larger margin if he wants to catch Moore: Based on the remaining votes, that same vote share would only get Carl to 48 percent (to Moore's 52 percent).

For those just joining us, here’s the scorecard in the presidential race tonight. Trump has won 12 contests thus far, while Haley has won only one (Vermont). We are still waiting for a winner to be projected in Utah and Alaska.

Now that the California Senate race has been projected, and more or less matches what we expected from pre-election polling, Schiff and Garvey will move on to the general election. Voters priorities in the state reflect its Democratic bent, giving us more hints that Schiff is well-positioned for a big lead in the general.

In polling before the primary, voters said abortion was the most important factor for their senate vote. In a late February University of California Berkeley/Los Angeles Times survey, 55 percent of likely California primary voters say that being "a strong voice in defending abortion rights" is very important to their Senate vote, more than any other candidate quality tested. For voters that say they plan to vote for Schiff, Porter or Lee (the top three Democrats in the race), 84 percent say defending abortion is very important, compared to just 15 percent among those who say they plan to vote for Garvey, the leading Republican.

Other top candidate qualities in the survey include being "a strong opponent of Donald Trump" (51 percent say this is very important) and supporting tougher immigration laws (46 percent). Among the top four candidates, Lee supporters were the only group among which a majority (63 percent) said supporting an immediate cease-fire in Gaza is very important, compared to 42 percent of Porter supporters, 33 percent of Schiff supporters and 13 percent of Garvey supporters.

In a few races, the Democratic Congressional Campaign Committee has endorsed a candidate ahead of the primary — a relatively rare step for the group. Most of those candidates are doing pretty well tonight. In Texas, Michelle Vallejo easily clinched the nomination for the 15th District, which is the only really competitive House seat in the state. In California, most of the DCCC's candidates don't actually have primary challengers, but one, Rudy Salas, is in a tough fight for a spot in the general election. Democrats are anxiously hoping to avoid a lockout in the 22nd District, where Salas is looking for a rematch against Republican David Valadao.

This morning, as Haley was dropping out, Trump sent a message over his social media platform Truth Social reacting to the results:

"Nikki Haley got TROUNCED last night, in record setting fashion, despite the fact that Democrats, for reasons unknown, are allowed to vote in Vermont, and various other Republican Primaries. Much of her money came from Radical Left Democrats, as did many of her voters, almost 50%, according to the polls. At this point, I hope she stays in the "race" and fights it out until the end! I'd like to thank my family, friends, and the Great Republican Party for helping me to produce, by far, the most successful Super Tuesday in HISTORY, and would further like to invite all of the Haley supporters to join the greatest movement in the history of our Nation. BIDEN IS THE ENEMY, HE IS DESTROYING OUR COUNTRY. MAKE AMERICA GREAT AGAIN!!!"
