Let me tell you how the "let's run our own liberal" strategy would pan out. Rooty Toot MIGHT pick up a few 'Rats, but nowhere near enough to overcome the number of conservatives who stay home.
Rooty Toot is probably the only candidate who will lose to Hitlery.
I agree, Rudy is unelectable and would almost certainly lose to Hillary - which is why the liberal media is hyping him as the Republican frontrunner. I think cross-over Dem’s would more likely vote for Ron Paul, than Giuliani. Anti-war sentiment in this country has gained considerably, while pro-abortion sentiment has waned (thankfully), or at least remained stagnant.
