WASHINGTON (AP) — An examination of Republican Herman Cain's comments and proposals raises questions about his grasp of issues he would face if elected president.

Cain has drawn unwanted attention for contradictory or unorthodox comments on abortion, China policy, immigration, torture and other matters. He has struggled to answer some questions about health policy and Libya.

On a few occasions Cain has quickly corrected his statements. Other times he has laughed off his critics and told them to have a sense of humor.

His against-the-grain style appeals to many conservatives. But others fear a lack of experience or even seriousness.
