Pence is the one to watch.
I’d take him as Hunter’s VP if DeMint is not interested.
The last sitting congressman to be elected to the presidency was James A. Garfield. Pence will have to run for governor or senator to be seriously considered. That is also why Hunter and Tancredo were never credible candidates - they didn’t have a big enough base to start with.
I agree, he’s got a real shot at being a nominee who can win. Sorry, but even if he could get the nomination Duncan couldn’t win a general election!
