Nathaniel, here's where I think the Trone electability argument ultimately fell short. This guy spent $62 million blanketing the state with positive advertising nonstop from September until today. If voters were going to respond to what he was offering, they would have done so already. The fact that by the end he was performing pretty similarly to Alsobrooks in head-to-head matchups against Hogan, and that his image was actually worse than Alsobrooks statewide, suggests to me that his money wouldn't have done him all that many favors in the general election. I still think he would have won, but only because I think any Democrat with a pulse and a decent voting record can win a Senate race in Maryland.

The Democratic primary for Maryland Senate has focused heavily on electability, with Trone arguing that Democrats should nominate him because he’ll have an easier time beating Hogan in the fall, whereas nominating Alsobrooks would risk giving Republicans a pickup opportunity. However, I’m skeptical that Hogan really has a shot in a state as blue as Maryland, no matter who Democrats nominate. What do you guys think?

With 41 percent of the expected vote reporting, Alsobrooks now leads Trone 53 percent to 43 percent, and we're starting to see projections for her from some outlets, such as the Associated Press. Probably the biggest sign of Alsobrooks's edge is that she's leading outright in places beyond the majority- or plurality-Black localities of Prince George's County (her home base), Baltimore City and Charles County.

In the last two open-seat Senate races in Maryland in 2006 and 2016, the Democratic primary featured one major Black candidate and one major white contender, and in each race the Black aspirant only carried those three places. But this time around, Alsobrooks is ahead in Baltimore County and running basically even with Trone in his home base of Montgomery County. All of this adds up to a lead that looks likely to hold up at this point.

At Alsobrooks’s HQ, a senior campaign adviser just interrupted appetizers and light dancing to announce that while the race hasn’t been called, they were “outperforming” their expectations for the night.

ABC has not projected Alsobrooks's victory, but is reporting her leading over Trone by 8 points. Connor Lounsbury, the adviser, said that the campaign was seeing particular improvements in Alsobrooks’s performance when comparing her vote-by-mail and and Election Day numbers.

Lounsbury also said that Alsobrooks was outperforming, by their estimations, in Montgomery and Baltimore Counties — pivotal places for the candidate.

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.
