Obama also cataloged a number of ways in which he believes Romney would be harder-line than Bush was.
"There are some things where Governor Romney is different from George Bush," Obama said. "You know, George Bush didn't propose turning Medicare into a voucher. George Bush embraced comprehensive immigration reform. He didn't call for self-deportation. George Bush never suggested that we eliminate funding for planned parenthood. So there are differences between Governor Romney and George Bush, but they're not on economic policy. In some ways he's gone to a more extreme place when it comes to social policy. I think that's a mistake."
