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.

Money can buy you a lot of things, but it's not all-powerful. Trone found that out the hard way tonight when he hit a ceiling of about 42 percent of the vote (with 61 percent of the expected vote reporting), despite spending untold millions. If Trone had spent $30 million less, I'm not sure he would have done all that much worse. If he had spent $60 million less, he probably wouldn't have registered at all.

It was obvious that money was a big part of victories elsewhere in the state and country. In Maryland's 3rd District, Elfreth was able to ride a wave of outside support to a comfortable but tough projected win over Dunn — without that money, I'm not sure she would have succeeded. And the third-place finisher, Lam, was not coincidentally the only other candidate to go on TV. In Maryland's 6th District, the only two Democrats with money to go on TV were also the ones to place in double digits, Delaney and Vogel, and the bigger spender won more votes. And in West Virginia's 2nd District and Nebraska's 2nd District, big spending by incumbent GOP representatives and their outside allies ultimately staved off underfunded challenges from right-wing opponents.

Anyway, my biggest takeaway is that Maryland has something to offer for everyone! And our flag is the best in the nation. With that: Good night.
