When U.S. Senate candidate Jim Barksdale stepped onstage to speak at the Bulloch County Democrats’ annual gala Friday night, he wore his hat, a rumpled riding cap, for a couple of minutes, letting everyone know he really was the man in the campaign ads. Then Barksdale doffed the hat and began to reveal his unusual stance as a Democrat who is a businessman – maybe even a rich one – emphasizing economic issues while running against an incumbent Republican. That Republican is Sen. Johnny Isakson, who after 40 years in state and national politics, including two terms in the Senate, is called an icon even by his challenger.
