Early voting began in Georgia six days ago. There is, of course, intense interest in both the state's Senate race, with University of Georgia football legend Herschel Walker challenging Democratic Sen. Raphael Warnock, and the governor's race, between Gov. Brian Kemp and Democratic challenger Stacey Abrams. Kemp is going to win, but the Senate contest is essentially tied. Its outcome might well determine which party controls the Senate.
