RE: I would love to see him as a Senator, though
How about Secretary of Health and Human Services?
Far better would be to eliminate the HHS department and all the rest, including but not limited to: EPA, HEW, NLRB, OSHA, FDA, NOAA, USDA...and many, many, many more. They're all run by a bunch of pointy-headed, pencil-necked geeks successful only in placing constraints on freedom.
