Well, I think the people who hate or distrust her are the sort who never vote anything but Republican. Certainly she'll get Kerry's percentage, at the very least.
Not necessarily, since some of those who voted for Kerry were more voting against Bush. In 2008, it would be a fresh start, and the election will be based on the candidates running (one thing which I tried to address on the 100% voter turnout thread). You have to take into account Republicans who did not vote for Bush, Democratic men who do not want a woman President, Anti-feminists, et al into the equation.
