Rudy is the only GOP candidate that can stop the Hildabeast. I find it amusing that many of my conservative friends worry so much about Rudy's lack of "purity" on social issues and so little about a Hillary presidency. Hillary will be nominated. Let's start dealing with that reality rather than some Bill Richardson fantasy nomination. Aint happening. Hillary wants it. She's not about to let some flea like Richardson get in her way.
Replace Hillary with Dean and Richardson with Kerry.
You can't really compare Hillary with Dean. Hillary has been a political "giant" for ages, whereas Dean was, to some degree, the frontrunner precisely
because of his underdog status, since he was seen as a breath of fresh air.
That said, I don't think she will get the nomination because Democrats will unite behind a "Stop Hillary"-candidate, ie. one out of Edwards, Richardson and Obama.
