Rick Santorum's stunning three-state sweep on Tuesday has revived his insurgent campaign, which had faded since its initial surge in Iowa. Now all eyes are on him to see if he can keep it going long enough to challenge Mitt Romney for the Republican presidential nomination.

Santorum, a former U.S. senator from Pennsylvania, is best known for his hard-line stances on social issues: abortion is wrong even in cases of rape, incest or threat to the mother's life; birth control is a license to do things in a sexual realm that is counter to how things are supposed to be; homosexuality is comparable to bestiality and pedophilia. But his presidential campaign has forced him to branch out in order to convince Republican voters that he is not a one-trick pony -- that he is not just a strong social-policy candidate, but a viable economic- and foreign-policy candidate as well.

Here is an overview of Santorum's positions on a variety of issues. For a more detailed profile, click here.
