While I supported Fred for Potus, I don't think he'd be a good VP choice -- he'd be way to old by Inauguration Day 2017. I don't think he'd be interested anyway.
If anyone in the remaining pool of rinos is smart, he'll pick someone who is NOT a candidate (ie. a true conservative).
He could be a Dick Cheney-type VP; no Presidential aspirations, but a solid conservative advisor to the President.
