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.

When Democratic Sen. Joe Manchin announced he was retiring in November, West Virginia's U.S. Senate seat became an almost automatic Republican pickup — and the GOP primary became the only game in town. But what was once expected to be a firecracker of a fight between Gov. Jim Justice and Rep. Alex Mooney has fizzled. Trump endorsed Justice in October, and the anti-establishment Club for Growth has not come through with the $10 million it originally planned to spend for Mooney, who is aligned with the far-right obstructionist wing of the GOP. As a result, Justice leads Mooney 60 percent to 26 percent in 538's average of primary polls of the race.

It's going to be a minute before we start to get primary results this evening, so allow me to make a humble suggestion in the meantime: Listen to the 538 Politics podcast!

Yesterday I sat down with my colleagues Nathaniel and Geoffrey and friend of the pod Leah Askarinam to talk about the recent The New York Times/Siena College swing-state polls and preview tonight's races. In case you missed it, the polling was pretty bad for President Joe Biden. He trailed former President Donald Trump in every battleground state except Wisconsin and lagged by 12 percentage points in Nevada.

But there are some caveats in understanding what those polls mean at this point in the cycle. Most importantly, it's less that Trump has picked up ground than that Biden has lost it, and a big question over the next five and a half months will be whether Biden can gain that support back. There's a lot more to say, but I'll let you listen to find out!

As far as tonight's races go, we mainly focused on the important Democratic Senate primary in Maryland, where things are looking truly competitive. We also hit on a couple of House primaries that feature people who were in the Capitol on Jan. 6, 2021 — one Capitol police officer and one Trump supporter. Check it out!

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!

This week's primaries are ovah, so we're calling it a night! Here are the most important races where ABC News has reported a projection:

- Maryland's Senate matchup is set. In the GOP primary, former Gov. Larry Hogan easily dispatched his primary opposition, giving Republicans their best possible nominee for what will still be a very tough general election in deep-blue Maryland. In the Democratic primary, meanwhile, Prince George's County Executive Angela Alsobrooks edged out Rep. David Trone in an expensive, hard-fought race. She now has the chance to become just the third Black woman elected to the Senate in U.S. history.

- In Maryland's 3rd District, state Sen. Sarah Elfreth won the very crowded Democratic primary, defeating Harry Dunn, the former Capitol Hill police officer who helped defend the Capitol during the Jan. 6 insurrection. Given the district's blue lean, Elfreth should win in November, adding more women to the House, where women are still just 29 percent of its members.

- Attorney General Patrick Morrisey won the Republican primary for West Virginia governor in a close race over former state Del. Moore Capito. He's heavily favored to win in November in this red state and will likely be a hardline conservative governor, as he's associated with the tea party wing of the party.

- In the GOP primary for West Virginia senator, Gov. Jim Justice easily defeated Rep. Alex Mooney, carrying all but four counties in exurban Washington, D.C. Justice will be heavily favored to win the seat being vacated by Democratic Sen. Joe Manchin, who announced his retirement last year.

- In the Republican primary for West Virginia's 1st District, incumbent Rep. Carol Miller fended off a far-right challenge from former state Sen. Derrick Evans, who'd previously served three months in jail after being found guilty in a case related to the Jan. 6 insurrection. She'll be favored to comfortably hold on to her seat in November.

- In the Republican primary for West Virginia's 2nd District, state Treasurer Riley Moore romped to victory over several other GOP candidates vying to succeed Mooney (who ran for Senate). Moore is the nephew of Sen. Shelley Moore Capito and the grandson of former Gov. Arch Moore; he'll be a shoo-in this fall for the deeply Republican seat.

- In Maryland's 6th District, which was vacated by Trone for his ill-fated Senate bid, Democrats went with a familiar name in their primary: April McClain Delaney, a former Biden administration official whose husband, John Delaney, held this seat for six years before Trone. On the Republican side, voters once again expressed their support for Neil Parrott, a local lawmaker who was the GOP nominee in 2020 and 2022. Delaney will be favored in the general election, but this is a seat that could get competitive under the right circumstances for Republicans.

- In Maryland's 2nd District, Democratic voters nominated Baltimore County Executive John "Johnny O" Olszewski Jr. to face off against Republican political commentator and frequent political candidate Kimberly Klacik. Biden won general election voters in this district 59 to 39 percent in 2020, so it's highly likely Johnny O will be the next representative of this northern-Baltimore seat.

- In Nebraska's 2nd District, Rep. Don Bacon easily turned back a primary challenge from right-wing Republican Dan Frei. That's bad news for Democrats, who would've had a much easier time beating Frei than Bacon in November in this swing seat.
