Voters across six states headed to the polls on Tuesday in the busiest primary election day of the 2026 midterm cycle, with races in Alabama, Georgia, Idaho, Kentucky, Oregon and Pennsylvania serving as a critical test of President Donald Trump's grip on the Republican Party. The contests span multiple time zones and feature closely watched battles at every level, from Senate seats to congressional districts where Trump has made his endorsements a central issue.
The marquee contest of the day is the Republican primary in Kentucky's 4th Congressional District, where incumbent Representative Thomas Massie faces Navy veteran Ed Gallrein, a challenger handpicked and endorsed by Trump. The president has publicly feuded with Massie over several policy disagreements, including the release of the Jeffrey Epstein files, making this race a direct referendum on Trump's ability to unseat a sitting Republican incumbent. Outside spending in the district has exceeded 32 million dollars, making it the most expensive House primary in American history.
In Georgia, the Republican Senate primary features several high-profile candidates competing to take on Democratic Senator John Ossoff in November. Two longtime Trump allies and the son of a legendary college football coach are among the leading contenders for the nomination, with the race seen as a bellwether for Republican voter enthusiasm in a state that has been fiercely contested in recent elections. The outcome will shape Republican strategy across the Sun Belt heading into the general election.
Alabama Republicans are choosing a nominee for the Senate seat being vacated by Tommy Tuberville, who is running for governor. Representative Barry Moore has secured Trump's endorsement for the seat, but faces a competitive field in a state where the presidential endorsement carries significant weight. Meanwhile in Pennsylvania, several contested congressional primaries are drawing national attention as both parties seek to gain ground in one of the country's most pivotal swing states ahead of the November midterms.
Oregon and Idaho round out the six-state slate, with Oregon featuring competitive contests in several House districts and Idaho holding its own set of down-ballot races. Political analysts describe this primary day as the clearest test so far of whether Trump's endorsement power has maintained its potency since he returned to the White House. Results are expected to begin rolling in as polls close throughout the evening, starting with Kentucky at 6 p.m. Eastern time. The outcomes will set the stage for what promises to be a fiercely competitive general election season across the country.
