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!

With Justice term-limited out of the West Virginia governor's office, the open-seat Republican primary features members of three old West Virginia political families: former state Del. Moore Capito, the son of Sen. Shelley Moore Capito; car dealer Chris Miller, the son of Rep. Carol Miller; and Secretary of State Mac Warner, whose father and brother were both state legislators. However, the front-runner is a relative newcomer to the state: Attorney General Patrick Morrisey (whose first campaign was for New Jersey's 7th Congressional District in 2000).

Trump has not endorsed in this race, but (so?) the candidates have been tripping over each other to prove they are the most pro-Trump — and, in a state that recently banned gender-affirming care, the most anti-transgender. For example, a pro-Morrisey PAC has hammered Miller for "pro-transgender events" (its language for drag shows and a free clothing closet for transgender students) at Marshall University, where Miller served on the board of governors until last year. Meanwhile, supporters of Miller have hit back at Morrisey for being a lobbyist for a "drug company that helps turn boys into girls" in an ad that also unsubtly pokes fun at Morrisey's height and weight.

Thanks to his ability to self-fund, Miller has spent twice as much money as Morrisey, $6.2 million to $3.1 million. However, polls indicate it hasn't done that much to boost his support. Instead, it is Capito who looks like he poses the biggest threat to Morrisey: Since April 1, he has risen from 16 percent to 26 percent in 538's polling average of the race, within striking distance of Morrisey at 33 percent. (Miller is at 20 percent, and Warner is at 12 percent.) Capito recently received the endorsement of Justice himself, and if he wins, would likely govern in the incumbent's back-slapping, deal-making style; the Club for Growth and Americans for Prosperity-endorsed Morrisey, though, is more of a hardliner.
