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.

Tonight, we'll be monitoring how candidates of color perform in primaries for governor, U.S. Senate and the U.S. House of Representatives. Overall, 47 people of color are running in these contests — 36 Democrats and 11 Republicans. Almost all of the candidates (44) are running in Maryland, which is one of the most racially and ethnically diverse states in the country.

The marquee Maryland race involving a candidate of color is, of course, the Democratic primary for Senate. If Alsobrooks makes it through both the primary and general election, she will be only the third Black woman ever elected to the Senate — although she may be tied for that distinction with Rep. Lisa Blunt Rochester, who is a strong favorite to win in Delaware.

Down the Maryland ballot, a number of candidates are running in the solidly blue 3rd District. In the Democratic primary, former Capitol Hill police officer Harry Dunn, who is Black, has been a fundraising machine but finds himself in a tight contest in against state Sen. Sarah Elfreth, who is white. State Sen. Clarence Lam, who is of East Asian descent, may have an outside shot of catching Dunn and/or Elfreth, while three other legislators of color — Dels. Mark Chang, Terri Hill and Mike Rogers — look unlikely to break through. On the GOP side, retired Air Force officer Berney Flowers, who is Black, has raised a bit more than his primary opponents, although the Republican nominee will have virtually no chance here.

In the blue-leaning 6th District, state Del. Joe Vogel, a Latino, is locked in a close race with former Commerce Department official April McCalin Delaney. A third contender, Hagerstown Mayor Tekesha Martinez, who is Black, has raised a sizable amount of campaign cash, too. In the mix in the Republican primary are Air Force veteran Mariela Roca, who is Latina, and former Del. Brenda Thiam, who was the first Black female Republican to ever sit in the Maryland legislature. However, this crowded race could go in a lot of directions.

Elsewhere, in the solidly blue 2nd District, Del. Harry Bhandari, a Nepali immigrant, looks like a significant underdog in the Democratic primary against Baltimore County Executive Johnny Olszewski. The GOP favorite in that seat may be Kim Klacik, a Black woman whose failed 2020 campaign in the solidly Democratic 7th District raised millions after Trump retweeted her campaign ad. She has raised far less this time around, and whomever Republicans nominate will be a huge underdog in November.

In the dark-blue 5th District, health care executive Quincy Bareebe, a Ugandan immigrant, has loaned her campaign more than $200,000 in her long-shot primary challenge to longtime Rep. Steny Hoyer. On the Republican side, Charles County GOP chair Michelle Talkington, who is half Black and half white, has no opposition in her primary. Reps. Glenn Ivey and Kweisi Mfume, both Black incumbents, should easily win renomination in their safe blue seats.

Outside Maryland, state Sen. Tony Vargas, who is Latino, is unopposed for the Democratic nomination in Nebraska's highly competitive 2nd District. And in Nebraska's special election for Senate, community advocate Preston Love Jr., who is Black, is also unopposed but will stand little chance in the general election. In West Virginia's dark-red 2nd District, Walker, who is Black, has raised a lot of money in the Republican primary but, as Nathaniel wrote earlier, looks like an underdog against Moore.
