She has never said that. What she said was: "So, for instance, I've tended to agree with those who do not favor federal funding for abortion, because I believe that those who hold a strong moral view on the other side should not be forced to fund it."
She's not saying that she is on the other side, she's saying that of the two sides in the debate those on the pro-life side should not be forced to finance those on the abortion side.
She stated that she is mildly pro choice. That's like being mildly pregnant. You either are or you are not. She supports abortion. Nuff said.
