Speaking to a room full of prominent US Catholic leaders Friday night, Senator Rick Santorum was challenged to run for the Republican Presidential nominaion.  Responding to a room already thick with applause, Santorum revealed that he was indeed "thinking about it" but asked for prayers and detailed his thinking on the matter.
His remarks came after his address to the closing dinner of the 12th annual Catholic Leadership Conference - an invite-only gathering of Catholic leaders from academia, law, media, medicine, and politics, as well as leaders of movements within the Church such as pro-life, pro-family and evangelization.  Posing the challenge was long-time legal, political, and media activist Keith Fournier.
