Is Herman Cain really prolife? Or is he just "personally prolife?"

I'm wondering if presidential candidate Herman Cain is just "personally prolife?" In a variety of interviews (here's a John Stossel interview) when he is pressed to say more than "I'm pro-life," Cain seems to indicate that he doesn't favor government making decisions about abortion. Politico has the latest regarding what Cain said during an interview with Piers Morgan:

His views on abortion, he said, should be seen this way: "I can have an issue on a opinion without it being a directive on the nation. The government shouldn't be trying to tell people everything to do, especially when it comes to social decisions that they need to make."

Cain certainly needs to be pressed by prolifers to clarify if he would sign prolife legislation if elected president. Recall that Cain refused to sign the Susan B. Anthony List's prolife pledge because it asks the candidate to "advance and sign into law a Pain-Capable Unborn Child Protection Act" because Cain felt only Congress could advance legislation.
