So if a candidate came along and had all the answers to the countries problems and could fix it all you would not vote for him if he was pro life and overtly religious? I have yet to see either issue effect a presidency either way but everyone is paranoid about it.
If they had all of the answers, I would likely overlook their religion as an issue. I'm an agnostic, not an atheist. I actually applaud Romney's actions that he takes on as a part of his faith. I think the whole idea of Mormonism is silly, and religion in general, but some people use their religion as a way to guide them through life and make the right choices. Good for them. Many folks are good people in general, without going to church or joining an organized religion. Others use religion as a crutch, many folks do actually, using it as a way to look down on others, and some of the most dishonest folks I've ever known (pastors included) come out with, "I'm a Christian...." as one of their first lines in a conversation. I tend to distrust them from that point on.
I generally tend to lean right, but an issue such as abortion, pro-life or pro choice, isn't a deal breaker for me. I'm snipped. The likelihood of overturning Row V Wade is so minute that to make it a major campaign issue is laughable. Really, the possibility of overturning Row V Wade has such a low probability of being reversed, as in 1 in a billion. A republican could simply say, "Row V Wade is the law of the land, it is what we live with today, but if you are pro-life, then don't get an abortion." Done and difused.
You can have an opinion, but the insistance of tilting at the windmill of abortion is one thing that the Republican party could slightly alter their stance on, state reality (it won't be changed), and they would gather a lot of folks in the middle. There are more folks in the middle at this point in time than any other time as both parties get more and more extreme.
