President Trump and Governor Brian Kemp are on opposite sides as Georgia voters go to the polls to pick a Republican nominee for Senate. Kemp backs former college football coach Derek Dooley while Trump endorses Representative Mike Collins.

The contest pits Trump against the governor of a key swing state in a test of influence within the Republican Party. The primary results will indicate which Republican leader holds more sway with Georgia voters in a race that could affect the balance of power in the Senate.
