Santorum would be my 2nd choice, but there’s no point in wasting a vote on someone not even in the top 10, so my de facto 2nd would be Trump. It’s a weak field if you’re looking for solid conservative values.
Santorum wouldn’t even win PA. I voted for Rick when he ran for senate, but he is dead meat in PA with conservatives due to his support for Arlen Specter. He once had a bright career in politics, but not so much now. Rick would be better off if he stuck to his movies.
