According to the historical record, when Georgia Senator Saxby Chambliss first ran against and defeated Max Cleland, he ran some incendiary ads that drew the ire of John McCain, who said:
"I'd never seen anything like that ad. Putting pictures of Saddam Hussein and Osama bin Laden next to the picture of a man who left three limbs on the battlefield -- it's worse than disgraceful. It's reprehensible."
We also know that as recently as the 2008 campaign, Keeper Of The McCain Hagiography Mark Salter was arguing in favor of McCain, saying stuff like:
"We're talking about someone who was willing to die before losing his honor! He would die!"
Since McCain is now officially stumping for Saxby Chambliss in the Georgia Senate race run-off, I am forced to conclude that the honorable Senator has become a member of the undead horde of zombies. Good luck, Georgia!
