Casey Cagle will wake up on Tuesday and win Georgia’s Republican governor primary election. No one ever doubted that Georgia’s longtime lieutenant governor, born in Gainesville and raised in Hall County, would come out on top on Tuesday. With almost 100 percent of voters recognizing his name and more than twice the campaign cash of anyone else in the race, Cagle’s four other major challengers haven’t raced for first place; even the day before the election, they proclaim they’re happily “surging” into second place. Cagle will win — but will he win by enough?
