True, Her campaign has been negative, but that's politics regardless of how we'd like to see it change. You'd really give the election to McCain rather than vote for her?

From my point of view that seems to be the sore loser strategy!
Lots of folks see no real difference between Hillary and Obama (I'm not one of them) but There are worlds of difference between Hillary and McCain. Continuing the legacy of the current administration would be a terrible thing to do just becuase of personal dislike.
