In the solidly red 4th District in central Washington, Republican Rep. Dan Newhouse once again finds himself fighting for his political life. Of the 10 House Republicans who voted to impeach Trump after the events of Jan. 6, Newhouse was one of only two who managed to secure another term in the 2022 election. This time around, Newhouse has two major GOP opponents in former NASCAR driver Jerrold Sessler, who finished behind Newhouse two years ago and initially received Trump's sole endorsement for this race, and veterans advocate Tiffany Smiley, the party's 2022 Senate nominee (who lost to Sen. Patty Murray). Until Sunday, it more or less appeared that Newhouse was the least pro-Trump candidate, Sessler the most and Smiley somewhere in between. But then Trump further muddled things by also endorsing Smiley, making this yet another primary where he's backed multiple candidates. If Smiley gains at Sessler's expense, that could have major ramifications for who makes it to the general election: Unlike in 2022, local Democrats haven't coalesced around one candidate, making it more likely that two Republicans could advance out of the top-two primary.

Newhouse does have a financial advantage, having raised almost $1.6 million, more than Smiley ($720,000) and Sessler ($409,000) combined. But pro-Smiley groups have spent $539,000 supporting her or attacking the other two Republicans, while pro-Newhouse outfits have invested $190,000. With an eye on winning over conservatives considering Smiley, Newhouse's campaign has attacked her for supposedly deceiving GOP donors by creating a political action committee ostensibly aimed at raising money for Republican candidates but that the Seattle Times found had mostly worked to retire Smiley's 2022 campaign debt. Newhouse also promoted his efforts to protect Washington farm land from purchase by "Communist China." For her part, Smiley has emphasized her outsider credentials, attacked Newhouse for voting to impeach Trump and claimed that Sessler would like to tax beef. Sessler has understandably played up Trump's support for his campaign as well as his endorsements from the far-right House Freedom Caucus and the state GOP.

Candidates of color are running in primaries across all four states tonight in both parties, although a majority of them are Democrats. They include groundbreakers, surprise winners from the last election and longshot candidates.

In Kansas, Rep. Sharice Davids, who in 2018 became the first openly LGBTQ+ member of Congress from Kansas and one of the first two Native American women ever elected to Congress, is running unopposed in her Democratic primary, but she'll find out who her opponent is this fall. The frontrunner is Dr. Prasanth Reddy, an Indian-American who immigrated with his family to Kansas as a child. Davids is a top target for the GOP in November and could have a tough time keeping her seat.

Criticism over the Israel-Hamas war is shaping up to be a decisive issue in many primaries. In Michigan, incumbent and "Squad"-member Rep. Rashida Tlaib, the first Palestinian-American to serve in Congress and a vocal critic of the Biden administration's approach to the Israel-Hamas war, is running unopposed in the 12th District seat. But next door in the 11th District, Ahmed Ghanim, an Egyptian-American who has called for a cease-fire, is making a long-shot bid to challenge incumbent Democratic Rep. Haley Stevens. Stevens won against another incumbent and Israel critic, former Rep. Andy Levin, on a pro-Israel platfrom after redistricting forced them to face off in 2022.

Unlike Tlaib, Rep. Cori Bush, a fellow "Squad" member and outspoken critic of Israel's war in Gaza, is facing a serious challenge today. In one of today's most contentious races, Bush has two Black challengers for the Democratic nomination, including St. Louis County prosecutor Wesley Bell, who's notably been backed by pro-Israel super PACs.

Meanwhile, both party's primaries for the critical Michigan Senate race include a candidate of color, though both are seen as long shots to win their respective contests today: Former Rep. Justin Amash, a Syrian- and Palestinian-American and a vocal Trump critic who previously left the Republican Party, is running for the Republican nomination for Senate, while actor Hill Harper, who is Black, is running for the Democratic nomination.

It's a similar situation in Missouri's governor race, where two Black Democrats and one Black Republican are running for the chance to be their parties' nominees, though the state's Republican Secretary of State, Jay Ashcroft, and Lt. Gov. Mike Kehoe are favorites to win the Republican primary. The winner will likely go on to win the general election in the safe red state.

Candidates of color are running for many positions across the state in Washington. Notable ones include Rep. Marie Gluesenkamp Perez, a Hispanic candidate who unexpectedly won against Republican Joe Kent in the state's 3rd District in 2022 and will face Kent once again this year. The crowded field in the open race for the state's governor also includes four Black Democrats and one Black Republican, but the frontrunner appears to be state Attorney General Bob Ferguson, who is white.

Democratic Rep. Shri Thanedar faces a primary challenge in the Detroit-based 13th District — although not the one many expected. Thanedar, who is Indian American, won an open-seat race in this plurality-Black and solidly blue district in 2022, edging out then-state Sen. Adam Hollier thanks in part to a crowded primary field. As a result, the city of Detroit has no Black member of Congress for the first time since the early 1950s, which — along with criticisms about his professionalism in office — has helped prompt opposition to Thanedar among some in Detroit's Black community and the Congressional Black Caucus. However, while Hollier was set to challenge Thanedar in 2024, he failed to make the primary ballot due to invalid signatures, leaving Detroit City Council member Mary Waters as Thanedar's main opponent.

Hollier's absence has put Thanedar in the driver's seat for renomination. Personally wealthy, the incumbent has self-funded much of the $7.1 million that he's raised, putting him light years ahead of Waters's $153,000. On top of this, outside groups have come in big for Thanedar, whether directly or indirectly. Pro-cryptocurrency group Protect Progress has spent $1.0 million to back him while Blue Wave Action, which has unclear ties, has spent $2.3 million to, er, muddy the waters. BWA has attacked Waters as corrupt, pointing to an influence-peddling scheme that resulted in a one-year probation for her. But BWA has also promoted the third (and minor) candidate in the race, which could potentially help split the anti-Thanedar vote. Waters's campaign has accused BWA of being in cahoots with Thanedar, although there's no evidence — and the group won't have to file information about its donors until after the primary.

The nonpartisan blanket primary race for governor has attracted no fewer than 28 candidates, after Democratic Washington Gov. (and one-time presidential candidate, remember that?) Jay Inslee announced last year that he would not seek reelection to a fourth term in office. However, very few of them have a shot of making one of the top two slots to advance to the November ballot.

The front-runner among Democrats appears to be Democrat Bob Ferguson, Washington's attorney general, currently in his third term (not to be confused with two other Bob Fergusons who had been running at the behest of a Republican activist, but later dropped out). Ferguson is leading the pack on fundraising, having raised close to $9 million according to the most recent financial disclosures, and has been getting plenty of support from state party leaders, including an endorsement from Inslee, though the party hasn't officially endorsed anyone. He does have some Democratic competition from Washington state Sen. Mark Mullet, though Mullet has struggled to get as much traction as the AG, and trails him in fundraising.

Another top contender is Republican Dave Reichert, a former member of Congress and former sheriff of King County — the most populous county in the state and home to Seattle. Reichert has raised the second-most funds of any candidate, with over $4.4 million. During his seven terms in Congress, he was a moderate with a record of being a consensus builder who wasn't afraid to buck the party line. That could serve him well in the Evergreen State, which hasn't had a Republican governor since the 1980s. Like Ferguson, Reichert is also facing some competition from within his own party — Semi Bird, a former Green Beret who made headlines when, as a member of the Richland School Board, he voted to overturn a mask mandate during the pandemic, in violation of state guidelines. Polls in this race show Reichert and Ferguson are likely to take the top two slots and be on the ballot in November, setting up a tight race between them for the governor's mansion.
