Each vote Gingrich gets is probably .98 of a vote Santorum could get. Who did the establishment cheat to win against in Iowa. Who does the Occupy movement try to destroy, while they are okay with the other 3 candidates?
I could be wrong, but it’s highly unlikely that Santorum could pick up 98% of Gingrich’s votes, if Gingrich left the race.
Maybe 30 percent.
