Rick Santorum announced Tuesday that he is suspending his presidential campaign, leaving Mitt Romney to wrap up the Republican nomination to take on President Obama despite still having GOP hopefuls Newt Gingrich and Ron Paul in the race.

Republican presidential candidate Rick Santorum caused a stir last month when he labeled college campuses "indoctrination mills" that enforce a strict adherence to "politically correct left doctrine." For conservatives, Mr. Santorum might as well have called the sky blue. But from the way liberal pundits pounced on his remarks, you'd think he had said something profoundly indecent.

Winning the Tuesday trifecta gives Rick Santorum a second chance to make a first impression. This will give him the momentum that his delayed Iowa victory could have given him.

AEI political expert Henry Olsen explains how Rick Santorum can capitalize on his victories last night by appealing to 'somewhat conservative' voters.

Does Romney still need to appeal to conservative Republicans, or should he start focusing on the broader electorate?
