If that's your criteria, why are you supporting Rudy?
He hasn't proven that he can do any such thing. To the contrary - when given an opportunity to run against Hillary!, he ran away with his tail between his legs.
Besides, if "he might win" is the best you can say about a candidate, he doesn't deserve your vote.
Though I am 100% against Giuliani, I am tired of hearing this slander. The man had cancer.
