The comments from Akin and others that you allude to were those of people who could only be classified as idiots. I don't care to have an idiot from any party serving in a national office, thank you. When are candidates going to be smart enough to view the landscape and be prepared to answer the "gotcha" questions that they know are going to come their way?
Conservatives are not going to win elections on social issues. If asked, we can state our position that "based on my religious beliefs, abortion is wrong". They need to further state that they understand that the social issue in question cannot be decided by legislation, but the candidate will support judges who will judge using the Constitution as written as their guide.
