The problem is Hillary is right & is just stating the obvious. Obama wasn't able to win key swing states & voters that he'll need to win in a general. If the party is really interested in picking the candidate who has the best shot, it's something that needs to be looked at.
I suppose my party will probably end up pretending that even though Obama outspent Hillary in states like PA & had plenty of time to win those votes that it doesn't matter because he has a padded pledged delegate lead with wins in red states that won't be wins in a general election.

Fair play!
