In what ways is Rudy Giuliani superior to Mitt Romney?
Giuliani isn't doing a complete makeover just prior to the election.
If you don't like Giuliani, don't vote for him, because what you see is what you'll get. I lived in Massachusetts while Romney ran for Senate, then became Governor, and now is running for President, and I see very little consistency in him.
Romney's qualifications for the job seem to be that he's telegenic and he says what some conservatives want to hear at rallies. Meanwhile his biggest accomplishment while governor was instituting a small-scale version of Hillarycare.
