The call center needs to identify and target progressives in SC. Coastal areas are the best place to start.
Huntsman needs to be courted. If I were Paul, I would go to him immediately and offer him VP if Paul is the nominee and Secretary of State if Huntsman is willing to join a coalition cabinet and support Paul in a third party run. Huntsman is the only other sane candidate in the GOP 6 calling for ending wars immediately. He is probably the only candidate Ron Paul could endorse among his 5 opponents. (I hate to leave Buddy Roemer out of the mix.)
It makes good tactical sense to make these offers to Huntsman. A Huntsman endorsement undermines charges of danger and extremism. It also makes sense for Huntsman since he is not going to be VP to a fellow Mormom. Ron Paul is closest to Huntsman in terms of policy and being the VP gets him closer to where he wants to be. It's maybe not a match made in heaven for either candidate but it would be a huge game changer for both of them. And more importantly, for the American people.
