The Republicans lost the "war on women" debate by being stupid, in particular 2 Senate candidates.
R's need to do the following when asked about it
"I am pro life and against abortion except in the cases of rape, incest and life of mother"
Thats it. Never mention it again. Repeat that line over and over.
And when you get in office, don't even address the issue. Go on to other more important things. Don't start passing "personhood" laws.
