If the neo-natal infant has not the right of life, then there is no right of life, liberty, property, and pursuit of happiness, because the last 3 presume the first, and the first presumes a beginning.
So far as the Libertarian candidate, I know that the Constitution Party candidate is totally pro-life with no mental reservations.
So far as Pres. Bush is concerned, I believe (?) he is rape/incest/life of mother pro-life. (There is a large distinction between that pro-abortion.)
So far as John Kerry, he has a lifelong, radical pro-abortion voting record.
I think you're exactly correct; at the present time Constitution Party would still be my first choice. However -- I'm pleased with Badnarik's statements, and hope he comes out forcefully in favor of the repeal of Roe vs. Wade consistently with his belief that abortion is murder, and Murder Law is the province of the State Legislatures.
As I mentioned, if he does so, he will be the 4th out of the last 5 Libertarian Presidential Nominees to call for the repeal of Roe -- which is a trend I can only applaud.
