Santorum fires:
"You win by giving people the opportunity to see a different vision for our country, not someone who’s just going to be a little different than the person in there," said Santorum. "If you’re going to be a little different, we might as well stay with what we have instead of taking a risk with what may be the etch a sketch candidate of the future.”
Romney defends:
A statement just now from Mitt Romney, via his campaign:
“I am in this race to defeat Barack Obama and restore America’s promise. I was disappointed to hear that Rick Santorum would rather have Barack Obama as president than a Republican. This election is more important than any one person. It is about the future of America. Any of the Republicans running would be better than President Obama and his record of failure.”
Romney spokesman calls Santorum line a "disgrace":
