Trone ended up spending just about $62 million out of his own pocket in Maryland's Democratic primary for Senate, but it wasn't enough for him to defeat Alsobrooks. It also left Trone just short of the all-time record for self-funding in a Senate race. In 2018, now-Sen. Rick Scott spent more than $63 million of his personal wealth on his successful campaign. (He's up for reelection this year.) But to put that in perspective, Scott spent that amount over the course of the whole cycle, whereas Trone shelled out nearly the same total for just the primary!

My main final thought for the night is that we've seen once again how powerful incumbency can be. Incumbents won against far-right challengers in primaries throughout the states. In the race I was watching, West Virginia's 1st, there was very little daylight between the two Republican candidates, Miller and Evans. Both were extremely loyal to Trump and the MAGA agenda, but Evans's candidacy largely hinged on him being more loyal to Trump than his opponent because he actually protested on Jan. 6, while Miller had avoided angering the base by voting against certifying the election. As we race toward an election that appears to be a 2020 rematch, the same 2020 spirit pervades many downballot races as well.

All the races we were tracking tonight have now been projected! What are everyone’s takeaways from the night’s results?

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.

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.
