ABC News is reporting that Miller is projected to win the GOP primary against her challenger, Evans. She has 64 percent of the vote with a little more than a third of the expected vote reporting.

Miller has stood by Trump and even voted to overturn the 2020 election results, but that didn't stop Evans from calling her a "commie RINO." The primary was more evidence that state Republican Parties have been tearing themselves apart over issues like loyalty to Trump and the 2020 election results, even as there are only small differences between candidates.

ABC News reports that Riley Moore, the state treasurer, will win the GOP nomination in West Virginia's 2nd District. He'll be a shoo-in for the general election this fall and will take his seat alongside his aunt, Shelley Moore Capito, who is set to be the state's senior senator at the beginning of next Congress.

This Olszewski ad might be my favorite of the cycle so far. He’s shamelessly capitalizing off the success of the American League East-leading Baltimore Orioles — nicknamed the O’s — one of the most exciting young teams in baseball.

ABC News reports that Kim Klacik is the Republican's nominee for Maryland's 2nd. Klacik also ran in 2020, when her ad that followed her walking the streets of Baltimore in a red dress and heels went viral. You could write a book about how Republican women campaign for Congress (and people have, FWIW). Klacik's would earn its own chapter, if I was writing it!

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.
