Her highest number is 48%, and there is no way it can go above that. Too many people hate her. The other thing to consider is turnout. Her presence in the race guarantees massive Republican turnout and low Dem turnout. The only way she can possibly win is if there is a strong center-right third party candidate.
Right about GOP turnout but wrong about 'rat turnout. She scores heavily in the "needy-greedy" demographic, and her secret "Biggest weapon" Billyboy will pull all the Blacks out of their chairs for sure. Win or lose, a clinton campaign will guarantee one of the highest turnouts, on both sides, in some time.
