Newt Gingrich is already trying to win the support of conservatives who had backed Rick Santorum in the Republican presidential race.
Shortly after Santorum announced that his campaign was coming to an end, Gingrich released a statement saying Santorum had shown "the power of conservative principles." The former House speaker vowed again to stay in the race until the convention, to give conservatives "a real choice." And he urged Santorum's backers to rally behind him.
Ron Paul, meanwhile, is congratulating Santorum for running a "spirited campaign" -- but Paul is describing himself as "the last -- and real -- conservative alternative to Mitt Romney."
As for Romney, he released a statement calling Santorum "an able and worthy competitor" and "an important voice in our party and in the nation."
A Republican source says Santorum spoke with Romney before today's announcement, and that Romney asked to meet with him sometime in the future.
