Tight primaries reshape elections from Georgia to Idaho

Voters in Georgia, Kentucky, Pennsylvania, Alabama and Idaho head to the polls for primaries today, including Kentucky’s high-stakes 4th District contest between Rep. Massie and Ed Gallrein—backed by outside groups and Trump allies—alongside Georgia’s open governor’s race and a competitive GOP Senate primary; Pennsylvania Democrats eye up to four House pickups (7th, 8th, 10th, 1st); Alabama’s primaries are affected by a new map for four districts; Idaho also votes for governor and its congressional delegation.
