"I have always been personally pro-life in my own life," he said, "In my view abortion is wrong except in the case of rape, incest, or when the life of the mother is threatened. But for me the question of what should government's role be was uncertain."

Romney goes on to say that his support for abortion rights changed when Massachusetts was debating embryonic stem cell research when he was governor. Now, he prefers leaving abortion up to the states.

Romney said he would prefer that "instead of having a one size fits all pronouncement for the entire nation as we currently have, that each state should be able to make their own choice in this regard."
