Some Santorum supporters moved to Paul and created a “Conservative Unity Slate.”
Fortunately, the largest bloc of "Saint Rick's" (as some Santorum haters have called him) people are Christian Conservatives and even though Gingrich experienced some past morality issues he was never pro-homosexual privileges nor pro-abortion.
At the primaries from now on, Newt should get the lion's share of Santorum’s people—that is, of course, if Rick's name has been removed from the ballots—if not I can only guess.
