Given all the challenges that face our current President and whoever follows him, why should their beliefs on pro-life or pro-choice be at all meaningful in choosing who will serve in the most powerful political position on the planet?

Personally, given the choices presented, I'd pick Gingrich and Cain. Gingrich has much greater capability and experience in manipulating the Washington "system" and Cain has some awfully good economic ideas which might find their way into legislation. I won't ask and I don't care how either of them feel on the question of pro-life or pro-choice.
