Republican presidential candidate Rick Santorum, now running in last place out of 11 GOP candidates, admitted Sunday that he may soon have to end his campaign. “You reach a point when you realize that you aren’t going to accomplish what you’re going to accomplish and you have to look out for the greater good,” Santorum told USA Today. “I’ve always believed in the greater good. I’m a person who believes in a cause and trying to make this country better, not about Rick Santorum and my own aggrandizement.”
