what states that Bush won, would vote for Hillary over Rudy? list them. what states that Kerry won, could Rudy win - NJ easily, probably NY, PA, etc. Unless you can make a case that Hillary beats Rudy in Texas or Missouri or Ohio - there is no Dem landslide in that race.
Let's suppose, for the sake of the argument, that Rudy Giuliani were to start the 2008 primary season as the uncontested GOP nominee for the White House -- and that he's popular enough that he has a 70% "approval" rating among the general public. From that 70%, we would have to make the following adjustments:
1. Subtract 5% (minimum) right off the bat for his political philosophy, which is just slightly to the right of John Kerry on most issues.
2. Subtract 3% for each of the following three (admittedly superficial, but very important) physical impediments -- his height (he's very short), his baldness (there has never been a bald president in the television age), and his speech pattern (he has a minor lisp).
3. Subtract 4% for the fact that he's got a vowel at the end of his name (no "ethnic" has ever been elected President).
4. Subtract 5% (again, this is a bare minimum) for the fact that he's not only an "ethnic" -- he's an Italian-American from New York (there hasn't been a New Yorker on a successful national ticket since FDR was elected in 1944).
5. Subtract 5% for all the media coverage that will be given to his silly cross-dressing escapades in that off-Broadway show while he was mayor of New York.
The way I see it, Rudy Giuliani gets trounced in 2008 -- he'll win 42% of the popular vote.
