Dexter was the big beneficiary of outside spending in the Democratic primary in Oregon’s 3rd District, and the early returns suggest those dollars really may have boosted her despite the fact she represents almost none of this seat in her current state legislative district. With 41 percent of the expected vote reporting, Dexter leads Jayapal 52 percent to 26 percent, so the outstanding votes are going to have to look pretty different for Jayapal to catch Dexter. Jayapal is trying to join her younger sister, Congressional Progressive Caucus Chair Pramila Jayapal, in the House.

The AP is projecting that Jack and Dugan will go to a runoff to decide the Republican nominee in Georgia’s 3rd District. With 92 percent of the expected vote in, Jack has 47 percent and Dugan has 25 percent. The Trump-endorsed Jack will therefore go into the June 18 runoff a strong favorite to win.

With 32 percent of the expected vote reporting in the Republican-on-Republican California 20th District special election, Assemblyman Vince Fong is leading Tulare County Sheriff Mike Boudreaux 74 percent to 26 percent. This is no surprise, since Fong had the endorsement of both Speaker Mike Johnson and ex-Speaker Kevin McCarthy, whose resignation triggered this special election.

With 29 percent of the expected vote reporting in the Republican primary for Oregon's 4th District, Air Force veteran and attorney Monique DeSpain leads former Keizer city councilmember, Amy Ryan Courser, 56 percent to 43 percent. DeSpain has an endorsement from Maggie's List — one of the GOP groups formed to elect more women to office that we've been tracking endorsements from this primary cycle. The winner of this primary will face incumbent Democrat, Rep. Val Hoyle in what's expected to be a competitive race.

Tonight, we'll be monitoring how candidates of color perform in primaries for the U.S. House of Representatives. Overall, 31 people of color are running in these contests — 27 Democrats and four Republicans.

The most high-profile primaries involving these candidates are arguably in Oregon. Jayapal, who is Indian American, faces a competitive primary in the state's 3rd District. One of her principal opponents is Morales, who is Latino. Meanwhile, in the 5th District, Bynum is seeking to become the first Black representative from Oregon. Two Latina incumbents in Oregon, Republican Rep. Lori Chavez-DeRemer and Democratic Rep. Andrea Salinas, should easily win renomination.

In Georgia, the main race of interest involving a person of color is incumbent Rep. David Scott, who faces six other Democrats of color in the majority-Black 13th District. Redistricting changed this seat significantly from the previous version Scott represented, but he's still probably favored. Flowers, who is also Black, is Scott's only challenger who really stands out, although he's not raised remotely as much as he did in 2022 or party activist Johsie Cruz Fletcher.

Elsewhere in Georgia, four Black incumbents — Democratic Reps. Sanford Bishop, Hank Johnson, Nikema Williams and Lucy McBath — all look set to win renomination in their solidly blue districts. Only McBath has any primary opposition, as she faces Cobb County Commissioner Jerica Richardson and state Rep. Mandisha Thomas, who are both Black, in the redrawn 6th District. Johnson, meanwhile, can look forward to a November matchup against Republican Eugene Yu, a Korean American and perennial candidate who is unopposed for his party's nomination in the 4th District.

In some of Georgia's solid red seats, the Democratic nominees will also likely be people of color. In the 14th District, retired Army Gen. Shawn Harris, who is Black, has raised a few hundred thousand dollars and looks favored to advance to November, where Greene will be heavily advantaged. In the 12th District, either 2022 nominee Liz Johnson or Army veteran Daniel Jackson, both Black, will be the Democratic pick against Republican Rep. Rick Allen, who'll likely win reelection. In the 11th District, businessman Antonio Daza, who is Latino, may be favored to win the Democratic nod to face GOP Rep. Barry Loudermilk, to whom Daza lost in the 2022 general election.

Meanwhile, Jonathan Richardson, who is Black, is the only person of color on a House primary ballot today in Kentucky; he's one of a few Democrats looking to challenge incumbent Republican Rep. Andy Barr in the safely red 6th District this fall. No candidates of color are running today in Idaho.
