That number is coming from the Guttmacher Institute or whatever its called. Its an way overinflated number to push the idea that abortion is so common and supported. Go look at the women in your own family and say that 1/4 to 1/3 have had an abortion. Probably not.
There is alot of apathy, mostly related to cost of living and war/oil. Saying the other side would be worse has never worked for the GOP. The adminstration toadies are tone deaf.
