Not everyone "knew" Chambliss was a sure thing, and I wouldn't be so blase' as to think that the Dems can't/won't unite on things like gun control, abortion, etc. Paranoia is one thing, but vigilance is NEVER wasted. Don't think that something won't happen, because you may end up with both feet in your mouth. The Republican party needs all the help they can get, even if it's "only" one Senator.
