I am being realistic. I'll vote for a candidate who promises to do all he can to discourage abortion. In fact that's what I did when I voted for Bush, both times - he never once said that he expected or intended to overturn Roe v. Wade. A president who has no problem at all with abortion is not capable of leading the country in any direction I want to go.
Pro-life or pro-choice is a mindset - either you believe human beings can be property, or you don't. All other policies follow from that. If there's two equally pro-choice candidates, then the election is six of one, half-a-dozen of the other. I will vote for the most pro-life candidate of either party in any election.
Reasonable people can discuss at what point the rights of the baby should outweigh the rights of the mother. Full disclosure, my position is "at conception." For me, partial-birth abortion is a deal-breaker - I will never vote for any candidate who supports that.
Okay, equate abortion to murder and I can stick with you, equate it to slavery and you've lost me.
