Santorum Is "In It to Win" It

Former Sen. Rick Santorum confirmed on Monday during an appearance on ABC's Good Morning America that he's officially running for president.

The staunch conservative, once the Senate's third most powerful Republican, last month formed his own version of a presidential exploratory committee, saying in an interview with Fox News, “In 2008 Americans wanted a president who they could believe in, but after two years they realized that what they needed is a president who believes in them."

Santorum represented Pennsylvania in the Senate for two terms from 1994 to 2006, when he lost a bid for re-election. He is particularly known for his views on abortion and homosexuality, the latter of which he famously likened to pedophilia and bestiality. He is currently finishing low in early polls, but his stances on social issues are expected to help him in important Republican primary states such as South Carolina and Iowa, where he plans to visit this fall for a series of appearances.
