Democrats' 22-person race in Maryland's 3rd District came down to two candidates (as expected). With 55 percent of the expected vote reporting, ABC News reports that Elfreth is the projected winner, and she leads Dunn 36 percent to 25 percent.

Question for the group: Is anyone surprised by Elfreth's win? I am a bit surprised, given Dunn's celebrity status.

We've been tracking how people of color are performing in primaries throughout this cycle, and there were 47 on the ballot tonight, 44 of whom were running in Maryland. Overall, seven are projected to win, of which Alsobrooks is probably the most notable.

Alsobrooks could make history as the third Black woman to ever win election to the Senate, though she could share that honor with Rep. Lisa Blunt Rochester, who is favored to win Delaware's open Senate seat. Elsewhere in Maryland, two Black Democratic incumbents, Ivey and Mfume, also won renomination. Klacik, whom Meredith discussed, won the GOP nomination in Maryland's 2nd District, but will be a huge underdog in November. It's a similar story for Talkington in Maryland's 5th District. In Nebraska, meanwhile, Vargas was unopposed for the Democratic nomination and will face Bacon in the state's purple 2nd District this November. And in one of Nebraska's Senate races, Love Jr. was unopposed and will very likely lose against Ricketts in the solidly red state. Beyond those individuals, it's unlikely that any other candidates on the list will win a primary tonight.

At Angela Alsobrooks's HQ in Greenbelt, excitement is getting more and more tangible — with results of her victory now called, the crowd is listening to some of her high-profile supporters in anticipation of her own appearance on stage.

Alsobrooks — who had a significant funding disadvantage compared to her much wealthier opponent — seems to have captured the majority of primary votes based on her slate of important endorsements from people, including Gov. Wes Moore and Reps. Steny Hoyer and Jamie Raskin.

"What do they say? Money can't buy you love," Maryland Lt. Gov. Aruna Miller said at Alsobrooks's election night party on Tuesday.

"I am so very proud of Angela Alsobrooks," Hoyer echoed, saying "both" Trone and Alsobrooks would have beaten Larry Hogan in a general election, but "Angela was the strongest candidate."

ABC News reports that April McClain Delaney is projected to win the Democratic primary in Maryland's 6th District, and that Neil Parrott is projected to win the Republican primary there. Both currently hold double-digit victories over their closest opponents, with over 55 percent of the expected vote reporting in each race. Delaney will start out as the favorite in the general election, but this is a district that could conceivably become competitive in a bad year for Democrats.

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.
