Several states held primaries Tuesday that offered tests of former president Donald Trump’s influence — and a look at contests that could reshape the midterm map.
What’s at stake
Republican infighting and high-profile endorsements made this primary day notable. Political reporters on the ground highlighted contests where Trump publicly favored challengers to incumbents, plus competitive Senate and House races where control and messaging are both on the line.
Kentucky: Massie vs. Trump’s pick
In Northern Kentucky’s 4th Congressional District, libertarian Republican Rep. Thomas Massie faced a Trump-endorsed challenger, Ed Gallrein. Massie has broken with party leadership at times — including objections to pandemic spending and public support for rivals in past presidential cycles — and Trump has been explicit that he wants Massie out. The race tested whether Trump’s endorsements can successfully unseat a long-serving incumbent who prides himself on independence.
Also in Kentucky, the open Senate GOP primary drew attention. Former Sen. Mitch McConnell’s old seat has become a focal point: Trump-backed former Congressman Andy Barr faced David Cameron, the state’s former attorney general. The result would indicate whether the Senate nominee tilts toward MAGA-aligned candidates or more traditional GOP choices.
Georgia and other Southern contests
In Georgia, several down-ballot primaries mattered as well. On the GOP side, Mike Collins, a Trump-aligned candidate, contested for the chance to run against Sen. Jon Ossoff; Derek Dooley — a former college football coach backed by Gov. Brian Kemp — was a notable alternative. Kemp’s influence was also part of a separate primary for his current seat, where Secretary of State Brad Raffensperger — who had public clashes with Trump after 2020 — faced a Trump-aligned opponent. Those results were being watched for whether Trump can move the statewide GOP in his direction when he is not on the ballot.
Pennsylvania: Democrats and the DCCC
Pennsylvania’s 7th Congressional District produced a contested Democratic primary drawing national attention. The Democratic Congressional Campaign Committee (DCCC) backed Bob Brooks, a retired firefighter and union leader, as the best opportunity to flip a seat that national Democrats see as vulnerable. Local voters and activists expressed mixed reactions to national intervention; the race was also viewed as an early test of Governor Josh Shapiro’s influence after he endorsed the DCCC-backed candidate.
Broader implications
Analysts emphasized two central questions: how much sway Trump still holds over Republican primary voters, and whether that sway translates to races where he is not the top of the ticket. A string of recent primaries suggested Trump’s criticism could be decisive — the loss of GOP incumbents targeted by Trump in other states underscored the possibility of similar upsets. If independents and local constituencies continue to support members who break with party orthodoxy, it could signal limits to Trump’s control over every GOP primary.
On the Democratic side, the DCCC’s involvement in primaries like Pennsylvania’s 7th showed national priorities in targeting vulnerable seats and testing whether machine endorsements help or hurt candidates in local, independent-minded districts.
Reporters and coverage
CBS News reporters Zak Hudak (Kentucky, GOP races) and Taurean Small (Pennsylvania, congressional races) reported from the ground, highlighting voter sentiment in battleground counties and the national implications of local primary outcomes.
Bottom line
Tuesday’s primaries were about more than individual nominations. They were an early measure of how national forces — Trump’s endorsements, governor and party leader backing, and DCCC intervention — interact with local dynamics. Results from Kentucky, Georgia and Pennsylvania were among the clearest early indicators of how strong (or limited) those forces remain as campaigns head toward the general election.
