How is Romney Different Than Bush?

Alex Castellanos, a former political adviser to Mitt Romney:

“At some point in a debate, Obama is going to turn and challenge Romney, saying, ‘Mitt, you have nothing new to offer. In fact, on social issues, foreign policy, taxes, spending, Medicare and everything else, you have nothing different to offer than taking us back to what George Bush proposed. That’s what got us into this mess.’ Romney has yet to answer that question. He has until the first presidential debate Oct. 3, in Denver, to find a response.”
