people who are voting Santorum likely wouldn't vote Paul regardless (with Gingrich, Perry, and other similar candidates in the field). so I don't buy the theory that pumping Santorum leads to a noteworthy detraction from Paul votes. what doesn't make sense is after they burn out all the other candidates, and its Romney v Paul, I think Paul has just as good of a shot at those neo-con/bachman/perry/gingrich/santorum voters as Romney does. this helps Paul a lot more than it hurts him IMO
