If Rick Santorum Couldn’t Say No To Specter, Can We Trust Him?

Mitt Romney has a web only ad out that smears Rick Santorum for supporting Arlen Specter while Specter was actually a republican. Specter has since changed over to a democrat. Santorum even spoke of this deal during the CNN debate earlier this week, but since then Specter has denied it ever happened. Now Romney is now using it against Santorum.
