An endorsement from President Donald Trump is worth a lot in Republican primaries. But is it worth more than $100 million in Georgia? Can it propel a congressman past an insurgent outsider in Alabama? Can it transform a candidate into a front-runner in Oklahoma?
Trump has been at the center of this year's midterm campaigns, and his influence will be tested in different ways Tuesday as four states and the District of Columbia hold primaries.
Among Democrats, the primaries will hinge on longstanding divides between progressives and moderates as the party tries to chart the best path forward to November.
Here's the latest:
2 open races set off a political scramble in heavily Republican Oklahoma
GOP Gov. Kevin Stitt is term-limited, and former U.S. Sen. Markwayne Mullin vacated his seat to replace Kristi Noem as Homeland Security secretary.
Republican Alan Armstrong, an energy executive, is filling the U.S. Senate seat for now, but state law prohibits him from seeking a full term as an interim appointee.
Rep. Kevin Hern, a four-term congressman endorsed by Trump, is running against four other candidates of lesser profile in the Republican Senate primary.
The GOP primary for governor is more crowded, with nine names on the ballot, including several prominent Republicans. That could lead to an Aug. 25 runoff if no candidate receives at least 50% of the vote to win outright.
California special election will fill former Rep. Eric Swalwell's term after his resignation
The Democrat stepped down in April following allegations that he sexually assaulted a woman twice, including when she worked for him, and other accusations of sexual misconduct.
Swalwell was a leading candidate for California governor at the time and dropped out of the race the same month. He has denied the allegations and said he will defend himself.
The San Francisco Chronicle first reported that a woman accused Swalwell of sexually assaulting her in 2019 and again in 2024. She told the outlet that she had been too intoxicated to consent.
Runoffs will decide GOP nominees for Senate and governor in Georgia
Tuesday's elections are needed after no Republican won a majority to clinch the nominations in the May primary.
In the Senate race, Rep. Mike Collins, a second-term congressman who calls himself a "MAGA warrior," and Derek Dooley, a first-time candidate and former football coach, are facing off. The winner will try to oust Democratic Sen. Jon Ossoff in a key November contest. Trump endorsed Collins on Sunday.
The primary for governor pits Lt. Gov. Burt Jones against billionaire Rick Jackson. Trump endorsed Jones last August. The winner will face Democrat Keisha Lance Bottoms, the former mayor of Atlanta, in November.
Polls now open in Washington, DC
Voting is underway in one of the city's most consequential primaries in a generation.
Democrats in the nation's capital have not had a chance to vote for a new mayor and new delegate to Congress in the same election since 1990, when gas was cheaper than $1.35 a gallon and George H.W. Bush was president.
