I am pro-choice. It's not that I don't think the unborn have rights, they do. BUT the protector of those rights should be the parents, not the state, IMHO. Abortion bans are also difficult to enforce. I'm not a woman so I'll just have to take you ladies on your word that this is a deeply personal and important issue.
Of course I am against all state funding of abortions on libertarian grounds.
It's a silly presidential issue. A president has very little say except to possibly appoint a supreme court justice or two. The vast majority of federal judges are prochoice. That makes overturning roe v wade extremely difficult. A constitutional amendment would require ratification by 3/4th of the states and so is effectively unachievable.
I think RP has the correct legal view that this is a 10th amendment issue that should get kicked back to the states.
