You're argument consists of a Quote -- without context -- from the radical Left's hysterical rantings against Giuliani. If he pisses of the Left so damned much, maybe he DOES belong at CPAC!
I was doing a Google search of older Giuliani stories, and came across the most amazing leftist attacks on him when he was mayor...Pictures of him with a Hitler mustache (a favorite among the lefties) labeled "Adolph Giuliani"; calling him "Hitler on the Hudson," and so forth. I figure if the left is that mad at him, he must have done some things right in NYC.
