Tuesday will be the busiest primary election day of the 2026 midterms so far, with voters weighing in on key contests up and down the ballot in six states across several time zones.
In several Republican primaries, President Trump's grip on his own party will be tested, like the challenge GOP Kentucky Rep. Thomas Massie faces from Trump-backed Ed candidate Ed Gallrein. Recent GOP primaries in Indiana and Louisiana have shown that Republican voters are willing to push out incumbents in their own party who Trump considers disloyal.
Meanwhile, Democrats are setting their sights on November with the hopes of flipping Republican-held seats. And their primaries will shed light on the issues that are motivating Democratic voters. At the same time, Democrats continue to ride a wave of enthusiasm and voter turnout since Trump returned to the White House last year.
