I’d put him at HHS, seems the obvious position. Surgeon General is less important
He might be considered for VP but I don’t think he’ll get it. He just doesn’t have the experience. It’s a pity he’s from Maryland, I’d love to see him make a Senate bid.
He’s originally from Detroit, and some people irged him to move back to Michigan and run for Levin’s Senate seat last year, but he wasn’t interested (and had his eyes on the presidency).
Stabenow is up in 2018. Given that the two likeliest GOP Senate candidates (Mike Rogers and Candace Miller) left Congress and pretty much are retiting from politics, and Gov. Snyder would not get conservative support in a primary, I think that Carson would be a terrific choice to take on Stabenow. But he should move back to Michigan now (something that would only help his quixotic presidential run).
