Mark K, agreed on the non-implanted zygote wording.
Heck, Paul Ryan has pretty much stated that the only abortion "aid" (read: funding of an abortion in part or whole by taxpayer dollars) he would back would be in examples where the mother's life is threatened.
He has also tried to pass laws that would limit such aid to "forcible rape" only, which wouldn't cover incest or statutory rape, and would place a burden of proof on the rape survivor as to the type of rape she endured. In addition, Ryan and others have worked to remove the taxpayer support for the public availability of several forms of contraception, including the unfortunately controversial "morning after pill" which gets confused by politicians with the "abortion" pill; the former preventing a pregnancy, the latter terminating one.
Personally, I don't like Ryan's politics when it comes to a woman's reproductive rights. He scares me. But only to the point that I think he could influence these things if elected VP...hint, he can't, unless there is a tie vote in the Senate, which I guess is possible. Still, I don't worry too much about that. I guess I should.
As sad as I think some of the Romney-Ryan positions are, I think most of those are conservative posturings (abortion, gay marriage, etc), and I don't see those things changing at all if they are elected...and I'm leaning more towards them than another 4 years of Obama.
