West Virginia actually has a history of casting protest votes against incumbent Democratic presidents in primaries, Irena. For instance, in 2012, Barack Obama beat total rando Keith Judd here just 59 percent to 41 percent. This year, Biden is winning a decent 71 percent of the vote, but he's especially weak in coal country in the southwestern part of the state — for example, winning just 49 percent in Mingo County. But these are no anti-Israel protest votes; coal country is a deeply conservative part of the country that nonetheless still has a lot of registered Democrats. These protest votes, therefore, are protesting the liberal direction that the national party has taken this century.

The only presidential primary-related news you should pay attention to tonight is that Jason Palmer, the Democratic winner in American Samoa on Super Tuesday, is on the ballot again today in West Virginia! With 69 percent of the expected vote in, ABC News has projected that Biden will win the Mountain State's Democratic primary, but Palmer is sitting in second place with 12 percent of the vote.

With Morrissey's projected win in the Republican gubernatorial primary, the GOP in West Virginia is nominating a slate of anti-abortion candidates. In Maryland's 6th, Parrott's projected win for the Republican nomination means that abortion could be a big issue in the competitive district in November. Maryland voters, like voters nationwide, are supportive of abortion rights, and this fall they'll decide on an amendment that would enshrine abortion rights in the state constitution. The projected Democratic primary winner, McClain Delaney, has championed abortion rights in her campaign. In an interview with The Baltimore Sun, Parrott said abortion should be left to the states.

Dunn's fundraising and national profile always made him look like the frontrunner in Maryland's 3rd, but Elfreth ran strong from the beginning, and the scant polling of the race we had showed her even with Dunn or ahead of him, before, during and after the UDP spending push (which, as Geoff noted, allowed the pro-Elfreth voice to be louder on TV than the pro-Dunn voice). And Elfreth's team was confident heading into today. I spoke with one of her allies this morning who was blunt in their assessment of the state of the race: "Elfreth will win it. She had TV plus organizing." Sometimes, it's that simple!

Since about the mid-1990s, Democrats have been electing more women to Congress than Republicans, and the gap gets bigger each cycle. A number of factors explain this disparity between the parties, but one is that the GOP continues to invest less in recruiting and financially supporting its female primary candidates.

There was some speculation that this might be changing. After the 2018 midterm elections, a handful of GOP groups aiming to elect more women cropped up after just four of the 42 new women who joined Congress were Republicans. That imbalance was a wake-up call for New York Rep. Elise Stefanik, who had reportedly recruited more than 100 women to run for Congress that year, but just one of them prevailed in November; most failed to emerge from their primaries. After the 2018 cycle, Stefanik started Elevate PAC as the Republican counterpart to EMILY's List. Stefanik announced she wanted to "play big in primaries," even though Republican leadership said it was "a mistake." Perhaps as a result, in the 2020 cycle, more Republican women ran in and won primaries than ever before.

But this cycle, Elevate PAC hasn't posted any endorsements to its website; Open Secrets shows that it has made contributions to primary candidates — but that list includes men, too, evidence that Stefanik may have other priorities this time around.

But Elevate PAC isn't the only GOP women's group that seems to be pulling back. We've also been tracking endorsements from Winning for Women, Maggie's List and VIEW PAC. Through today's primaries, Winning for Women and Maggie's List have endorsed just two non-incumbents (Wendy Davis, who lost her primary last week in Indiana, and Laurie Buckhout, who won her March primary in North Carolina). VIEW PAC is outpacing these other groups in endorsements, but it has still endorsed only five non-incumbents (two of whom have won their primaries thus far).

Today, there is one Republican woman running in an incumbent-less primary with support from VIEW PAC: Mariela Roca, an Air Force veteran, is running in Maryland's 6th District. However, she faces an uphill battle against two former state delegates, Dan Cox and Neil Parrott.

The primaries aren't over, so we don't yet know if the GOP is slipping when it comes to nominating women. But preliminary evidence from the Center for American Women in Politics suggests a decline. The number of female Republican House candidates is down by 38 percent from 2022 to 2024 in states where filing deadlines have passed.

CORRECTION (May 15, 2024, 3:15 p.m.): A previous version of this post stated that Winning for Women and Maggie's List have only endorsed one non-incumbent through today's primaries. The post has been updated to include Laurie Buckhout of North Carolina's 1st Congressional District, whom both organizations have also endorsed.
