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!

Meredith, the race seemed very close in a way that made it hard to project just who would win. It's true that Dunn raised a very large amount of money and definitely had a lot of traction online. But Elfreth raised a fair bit herself and actually represents part of the district in the Maryland state legislature, whereas Dunn didn't have an initial base of support as he hails from outside the seat in Montgomery County. Most critically, Elfreth received ample outside support from United Democracy Project, the AIPAC-associated super PAC. So while Dunn had raised $4.6 million to Elfreth's $1.5 million, UDP spent $4.2 million in support of Elfreth while Dunn had no outside help. To be clear, a candidate's campaign dollar goes farther when booking ads than for outside groups, but as Jacob pointed out in late April, the combined broadcast ad time bought by Elfreth and UDP sometimes outdistanced Dunn during the campaign.

Welcome to 538’s live blog of the May 14 primaries in Maryland, Nebraska and West Virginia! But this is no ordinary live blog. Today, my friends, is arguably the most interesting downballot primary day of the cycle.

The headliner today is the Democratic primary for Maryland’s open Senate seat. The Old Line State could become only the third state to elect a Black female senator, but a wealthy white congressman has spent nearly $62 million (!) to make sure that doesn’t happen. Some have argued that this should-be-safely-Democratic seat could be competitive in the fall if Democrats nominate the wrong candidate, but is that really true? We’ll discuss.

Elsewhere, Republicans could cripple their chances of winning Nebraska’s swingy 2nd District in November if they nominate a far-right primary challenger over a moderate incumbent. Meanwhile, we have one race tonight where someone who spent three months in jail for storming the Capitol on Jan. 6 could return there as a U.S. representative, and another that includes a former Capitol Police officer who was there that day.

And that’s just scratching the surface; we’ll be going deep on primary races up and down the ballot. The polls close in West Virginia at 7:30 p.m. Eastern, in Maryland at 8 p.m. Eastern and in Nebraska at 9 p.m. Eastern. Plan your evening accordingly!
