Polls are now closed in the Golden State, where a special election is taking place to fill the seat of former House Speaker Kevin McCarthy for the remainder of his term. State Assemblymember Vince Fong led in the regular top-two primary two weeks ago, and is favored to ultimately win this race as well. But results in California usually take quite a while to fully come in since a large proportion of voters vote by mail. And it might not end with today's contest either: If no candidate receives more than 50 percent of the vote today, the top two vote-getters will advance to a special general election in May.

Moreno’s nomination in Ohio continues a trend of Republicans entrusting their Senate hopes to a coterie of very wealthy men (and one woman, Nella Domenici in New Mexico). In almost every single competitive Senate race, the likely Republican nominee is a politically inexperienced but very wealthy man, each of whom is self-funding to some degree. While Moreno isn’t as wealthy as Tim Sheehy in Montana, Eric Hovde in Wisconsin or Dave McCormick in Pennsylvania, he certainly fits the mold. And if Republicans come up short in their efforts to flip the chamber this fall, I think there will be a lot of focus on how the party eschewed candidates with experience winning races in favor of neophytes, especially when Democrats have such strong incumbents.

Of the 29 anti-abortion Republican candidates we're tracking, 15 have been projected to win per ABC News, including 6 incumbents. Twelve challengers are projected to lose their races (though, of course, many were running in the same contests, like the crowded Ohio 2nd District race). In the only race on this list that's not yet projected, Illinois's 12th District, incumbent Mike Bost is leading Darren Bailey — both are on the list. With abortion shaping up to be an important issue in the fall, these candidates have all made pro-life statements without saying abortion should be left to the states. That could signal their willingness to support a national abortion ban, as some Republican and national anti-abortion groups are advocating for.

In Ohio’s 6th District, Michael Rulli is projected to defeat Reggie Stoltzfus in the Republican primary, according to ABC News. Rulli currently leads by about 9 percentage points in the regularly scheduled primary and 8 points in the special election primary to succeed Rep. Bill Johnson, with over 80 percent of the expected vote reporting in each. Because the district is solidly Republican, Rulli will likely be the next member of Congress. A special election in a few months will send him to D.C., where he’ll fill out the remainder of Johnson’s term.

With 68 percent of the expected vote reporting, Bost leads Bailey 53 percent to 47 percent in the Republican primary in Illinois's 12th District. But Bost looks to be on pace for a potentially narrower win — and perhaps could even lose. After the 2020 Census, Illinois Democrats drew a gerrymander that packed more Republican-leaning turf into Bost's 12th District in southern Illinois, which he had represented since 2015. About half of the new-look version of the seat had been in Bost's old district, but much of the eastern part of the seat was new to him. Meanwhile, Bailey's old state Senate seat made up a large chunk of that eastern section, giving him a geographical base of support for this primary despite facing the incumbent Bost.

As things stand, Bost is winning about 70 percent of the vote so far in the area he represented prior to the 2022 election, while Bailey is winning 73 percent in the counties that were in his old state Senate seat. The two are running about even in the remaining turf. The good news for Bost is that more of the primary vote will likely come from his neck of the woods. But the good news for Bailey is that more outstanding votes are likely left to be counted in his area of the district. A back of the envelope calculation based on each candidate's showing so far would put Bost up about 51 percent to 49 percent by the time all is said and done, but that is too close to call.
