"I'm telling you McCain would attract a significant portion of the liberal vote."
Absolutely not! I don't know a single liberal that would vote for McCain over Hillary. They may like McCain more than they do most Republicans, but not enough to vote for him over a Democrat. He will on the other hand lose alot of conservatives both Republican and Democrat. They won't necessarily vote for Hillary, but alot of them will probably not vote or vote 3rd party. Also some conservative Democrats will vote for Hillary becuase McCain doesn't give them enough reason to overlook party loyalty. If McCain were president in 2002 I don't think I would have started voting Republican.
If you say so, but lets put it this way McCain is much more likely to get the "conservative democrat" vote then he is to get my vote.
