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!

Money can buy you a lot of things, but it's not all-powerful. Trone found that out the hard way tonight when he hit a ceiling of about 42 percent of the vote (with 61 percent of the expected vote reporting), despite spending untold millions. If Trone had spent $30 million less, I'm not sure he would have done all that much worse. If he had spent $60 million less, he probably wouldn't have registered at all.

It was obvious that money was a big part of victories elsewhere in the state and country. In Maryland's 3rd District, Elfreth was able to ride a wave of outside support to a comfortable but tough projected win over Dunn — without that money, I'm not sure she would have succeeded. And the third-place finisher, Lam, was not coincidentally the only other candidate to go on TV. In Maryland's 6th District, the only two Democrats with money to go on TV were also the ones to place in double digits, Delaney and Vogel, and the bigger spender won more votes. And in West Virginia's 2nd District and Nebraska's 2nd District, big spending by incumbent GOP representatives and their outside allies ultimately staved off underfunded challenges from right-wing opponents.

Anyway, my biggest takeaway is that Maryland has something to offer for everyone! And our flag is the best in the nation. With that: Good night.
