I think Torie sells Huckabee short: he's a very effective born politician and would be a boon to the bottom of Romney's ticket. I think Romney should probably go for a Rubio or a Christie, but Huckabee is not a bad choice at all.
Huck is a protectionist - a deal killer. He also took an unseemly amount of gifts as governor, totally in the hundreds of thousands. Born poor, he is transfixed by the gleaming gold - which he is now actively pursuing. Anyway, he is not preparing to be VP clearly. I don't think he is not in the hunt.
