For those who have endured Georgia’s longest runoff election ever, the July 22 finish line is finally coming into view. Voters and candidates are learning there is a big difference between four weeks, which was how long these campaigns used to last, and nine weeks, the runoff duration ordered by federal Judge Steve Jones to give overseas voters more time to mail in their ballots. The biggest race on the election ballot is the Senate Republican runoff between Rep. Jack Kingston and business executive David Perdue.
