You take Romney’s word for this? Keep in mind that he is a congenital liar.
It’s very hard to see a comment like this as anything but an attempt to undermine Santorum and portray himself as Mr. Important.
Don’t waste your vote or money
Romney’s also a godawful campaigner. If I were his handler watching him say him and Santorum are “not much different on the issues” I would be tearing my hair out. That’s a huge opening for Newt. He can now run ads linking Romney and Santorum together and more easily explain how he is by far the candidate of bolder, truly conservative change compared to the status quo that MittRick has to offer.
