South Dakota's House has taken the next step towards banning abortion and the bill will now go to the state Senate.
Supporters are pushing the measure in hopes of drawing a legal challenge that will cause the US Supreme Court to reverse its 1973 decision legalizing abortion.
The bill banning all abortions in South Dakota was passed 47-to-22 in the House.
Amendments aimed at carving out exemptions for rape, incest and the health of women were rejected.
The bill does contain a loophole that allows abortions if women are in danger of dying. Doctors who do those abortions could not be prosecuted.
A self-defense exception is a no-brainer, but I'm also sympathetic to people who want exceptions for rape and incest. My feeling on those two points isn't very strong, and I suspect that very few abortions are performed for those reasons.
