"I can confirm, Laura, that I do have a soul."

That's former Massachusetts Gov. Mitt Romney, talking to radio host Laura Ingraham about the new book "Game Change," in which former Arkansas Gov. Mike Huckabee is quoted as saying, "I don't think Romney has a soul."

This isn't a religious argument, though Romney also made a joke about that; it's about the sense many observers have -- and apparently, many of his opponents as well -- that Romney's principles are very flexible and depend upon electoral politics.
