I am not sure about the other candidates, but I believe Santorum is better on the life issue than most:
In addition to which he has, like Palin, had to confront the worst case life and death scenario in his personal life, so this is not political theory for him, but a practiced reality.
Disclaimer: I am not a shill for Santorum. I am a dislocated Palin supporter and I am backing Cain because I think he is a trustworthy person who is a genuine Reagan conservative, can pull off the leadership gig, and has the juice to beat Obama.
Which gets to the basic problem we have this cycle: You don’t elect policies to office; you elect people. Given a true cafeteria candidate, I suppose I would splice Santorum’s coherent prolife policy together with Cain’s persona (leadership, communication, character, etc.), along with Palin’s “sudden and relentless” reform mentality, not to mention her foresight.
However, inasmuch as the foregoing fantasy candidate is not gonna happen, I’m taking what I think I can get. Furthermore, in the absence of Palin, I reserve the right to adjust as the game progresses. Cain can do this. He’s got the ball, and he’s in the red zone. It’s up to him. I am rooting for him.
Cain/Palin 2012
Thank you for the answer on who has the coherent pro-life platform. I don't think Santorum has the juice to win and he really rubbed me the wrong way when he took up the distortion of Cain's pro-life position that the libs and Paul-bots are spreading around.
