What to watch in May 19 primaries

Seven states hold primaries on May 19, with significant races in Kentucky and Georgia. In Kentucky, Rep. Thomas Massie faces a heavily-funded primary challenge over his Israel stance, while the race to replace retiring Sen. Mitch McConnell sees Trump-endorsed Andy Barr leading. In Georgia, the gubernatorial race involves Trump-backed Lt. Gov. Burt Jones competing against healthcare CEO Rick Jackson and others, with gerrymandering implications for 2028.
