Sorta like a teetotaler who gets drunk every night.
Not much. A teetotaler, by definition, does not imbibe. I don't say Giuliani is the perfect candidate. But I think he is strong on the WOT, which to me is the #1 issue. He also dismantled the Mob in NYC, repeatedly slapped down the media, and governed a city that for 40 years prior to his administration was ungovernable. We could do worse.
