More detailed surveys show that the middle 50% (56% in this survey) who are opposed to the complete legalization or the complete illegalization of abortion is mostly composed of people who oppose abortion except for rape, incest, or the life of the mother.

This survey makes no attempt to correlate the issue to political affiliation so this statement is completely unsubstantiated. Surveys that do indicate increasing polarization about the abortion issue within both parties.
If Karl Rove wants social conservatives to vote for his candidate, he just might have to make sure his candidate actively supports the policies that are important to these social conservatives.
