Democratic Sen. Max Cleland is in an ever tighter campaign against the GOP challenger Saxby Chambliss. I think the main thing holding his campaign together is the (apparently) enthusiastic support he gets from conservative Democrat Senator Zell Miller. Also, it helps that Democratic liberals (e.g., Daschle or Clinton) have not openly campaigned for him. Zell is giving Cleland cover. The Presidents trip to Georgia today indicates that the Republicans think they have a shot at the seat, else he wouldnt have gone down. This story from the Atlanta Journal-Constitution makes all this pretty clear.
