Rick Santorum suspended his campaign today, calling the race "as improbable as any race you will ever see for president." The former US Senator, who had won 11 states in primaries and caucuses, announced his decision in Gettysburg, just two weeks before the primary in his home state of Pennsylvania. He asserted that pulling out of the battle for the Republican nomination would not deter him in the battle to unseat President Barack Obama. Reid Wilson is editor in chief of the National Journal's Hotline.
