I keep hearing how a significant portion of Hillary supporters would Vote Mccain if Obama got the nomination.

Just 2 things to say about that:

1, I don't really believe it - these are people in the heat of the campaign and they'll say anything. When the inevitable occurs and Hill ends up rallying behind Obama as the nominee, most of that animosity will disappear.

2, anyone who's willing to trade a Hillary vote for a McCain vote is so stupid they probably shouldn't even be voting.
