I’m a Gingrich supporter, like you. But Santorum’s my 2nd choice (or tied with Perry for #2.) I found him answers, particularly on foreign policy, to be very coherent & intelligent. I think what damaged him for a while was his constant whining about not getting time during the debates.
Santorum is straight out of Vice President central casting and the perfect Vice President for Newt. He’ll help balance the ticket with one fat guy and one skinny guy.
