Gallup:Biden choice has little impact. Will that choice be the defining moment when remembering Obamas loss?

The bottom line is that people don't vote for the person at the bottom of the ticket. Biden will not help Obama in any significant way at all. He sounds like a logical choice in theory, but in reality it's not going to work out that way. The only person who could have brought more of the Hillary voters over to Obama is Hillary herself (as VP). Close to 50% of Hillary supporters don't back Obama; Biden isn't going to put much of a dent in that number.
