Despite the hard work being done by Senators like Bill Frist to generate popularity out of thing air, polls say that Rudy Guiliani has a healthy lead over Frist and McCain. It seems to be that the popularity of his book Leadership coupled with his years as mayor of New York have won him not only a chance to speak during last year’s election events, but perhaps to participate directly in them next time.
Giuliani hasn’t exactly mentioned publicly that he’ll be seeking the presidency, but he has plenty of time to do so. If he wants to, he can quietly build support the way Hillary is doing before giving any formal declaration of an intent to run.
