Hillary's negatives are way too high to be elected president, so I say she should go for it. It will be fun to see the Hildabeast and Obama Hussein beat each other down. I've got the popcorn ready.
Don't forget, thirty percent of the electorate would vote for Charles Manson if he was the Democrat candidate. All she has to do is deceive another 21% (or less, if she can get a stalking horse third party candidate to run against the Republicans).
