Hopefully the real issue is Hilary's weakness as a candidate.
Given how long she's been in the spotlight, I think people already know all they're going to ever learn about Hillary. However, all they've seen of Giuliani is NYC's reaction to 9/11. They haven't seen his drag-dressing cousin-kissing hippie ways yet.
Giuliani is a loss for the party, plain and simple. He's not going to get into office, and even if he did, it'd be a disaster for us.
