Pro-Life forces are positively gleeful. With the Kennedy vacancy on the Supreme Court their prospects for getting Roe v Wade overturned have never been better.
Of course we ourselves are Abolitionist and were we to form a pro-life organization we'd call it The John Brown Society*.
But in overturning Roe v Wade, we see only great risk for Republicans.
Recall that if Roe v Wade is overturned the issue simply devolves to the states. Some states would pass strong legislation to protect abortion, others would ban abortion strait away.
Thus abortion would become the penultimate issue for several elections. Pro-abortion forces will be extremely motivated, and swing voters that want abortion legal in some way** may well vote Democrat in local races in swing states like Ohio, Florida, and Pennsylvania.
I'd hate to upend the political situation as it now stands.
*That's something like 60% of America, folks.
