What to watch in Tuesday’s primaries in Kentucky, Georgia and elsewhere

Key Points:

• Six states—Alabama, Georgia, Idaho, Kentucky, Oregon, and Pennsylvania—are holding key primaries on Tuesday, marking one of the busiest days in the 2026 election calendar.
• President Trump is intensifying his "revenge tour" against GOP opponents, notably targeting Rep. Thomas Massie of Kentucky in what could become the most expensive House primary in history, with spending exceeding $30 million.
• Georgia Gov. Brian Kemp’s endorsement of political newcomer Derek Dooley in the competitive Senate primary is a significant gamble, with the race likely headed to a runoff; Dooley’s failure to advance would be a major setback for Kemp.
• Democrats aim to maintain momentum in Georgia’s state Supreme Court races, where liberal challengers seek to unseat conservative incumbents in effectively partisan contests that could influence the court’s future balance.
• Pennsylvania Gov. Josh Shapiro is expected to have a relatively smooth reelection but faces a critical test in supporting firefighter union leader Bob Brooks in a competitive 7th Congressional District primary, which could impact Shapiro’s broader political influence.
