I think Mitt's base really really wanted Ryan and they will be happy. However, from what I have read/heard about Ryan's Medicare reform (voucher) plan, I think the President's team can and will make that a real issue and it's an issue than people take very seriously.
I can't help but sense that Mitt is easily swayed to do whatever the far right want him to do. Or maybe it's him, hesitating to take a CLEAR stand on any one issue. He's really different than I thought he'd be.
