Obama & Hillary sound like the only winning ticket for the Dems! Many voters (myself included) don't agree with how American problems are being solved by our current administration. The Romney/Ryan campaign needs to run hard while things are still up in the air to secure as many votes as they can. Last election I struggled to make a choice, this time my decision has already been made.
I think that he will keep Biden unless they are polling really bad & than Hillary might just be their October surprise. I hope not because in my opinion I think that it would give them a boost & they might win & we can't afford another 4 years of the same thing.
