Obama has made his views on abortion pretty clear when he opposed the Illinois BAIPA (Born Alive Infant Protection Act).
OK, to be fair, I suppose he didn't, He said he supports infanticide, not abortion. I guess we still need to wait on that abortion position.
I wrote a bit about it here

I think that is about as far from responsibility as you can get, allowing a mother to kill off a child because it was accidentally born.
