You are ignoring the fact that the reason Santorum supported Arlen Specter over Pat Toomey was, that Specter was the chairman for the judicial and the nominations of Samuel Anthony Alito, Jr., Associate Justice, and John G. Roberts, Jr., Chief Justice of the United States, who were both nominated by President Bush was at stake. With out Arlen Specter, they would have never made it.
Unlike what Newt got for his Dede Scuzzyflava support...ZIP, ZERO, NADA!
