Chuck Baldwin opposes abortion even in the case of rape or incest.
John McCain (R) gives exception for abortion in the case of rape, but really he does not require that anyone test for rape, so it is a loophole that anyone can claim and still get abortion on demand.

John, that's not good enough! Goto a prison of pointlessness; Do not pass "go"; Do not collect 200 electoral colleges.
Obama (D), isn't bothered by partial birth abortions or any other kind of unborn baby slaughter, though we don't know for sure if he would have been bothered had his mother killed him. (Of course such a senseless death would be no less tragic than any other.)
Obama's stance isn't merely mavericky, like John's, rather it is a bloodthirsty shame.
My commandment to you is to love those who have wronged you and forgive them, starting with your own self; and be patient with those whom you have wronged. ~ Jesus [Letters from God and His Christ - Volume 6 - Bear Fruit According to the Spirit of Truth]
