WEST DES MOINES — Presidential candidate and former U.S. Sen. Rick Santorum (R-Penn) says he wants to be “known as the strongest, most-principled, authentic conservative” candidate in the 2012 elections, and emphasized his activism on social and cultural issues, specifically abortion, on Tuesday.

“It’s one thing to go in front of a pro-life group and say you’re pro-life,” Santorum told the media after a private meeting at West Des Moines’s Informed Choices Medical Clinic, which recently opened as a clinic offering women limited reproductive health care services that exclude contraception and abortion. “(But) it’s another thing to go out and actively work as an elected official to make real changes to culture when it comes to this issue.”
