We’ve talked about the difficulty facing Democratic primary voters who must choose between two candidates for governor holding similar positions on basic issues important to Democrats. That situation is more than doubly difficult in a Republican primary where the five leading candidates are all trying to run to the right of each other. The basic dynamics of the primary haven’t changed. Lt. Gov. Casey Cagle is the frontrunner, with a commanding 30-point lead in the polls over his closest challenger – but he is still about 10 points shy of winning without a runoff. That leaves Cagle hoping to pick up those last few points while the others fight and claw to see who’s the most conservative and most deserving of forcing their way into a runoff.
