Jim Geraghty and others have advocated the idea of Mitt Romney assuming a “car czar” role. I remain a Romney fan for many reasons; one of them: he’s a capitalist and a good one at that. If one of the Big Three called him up and asked him to get in its driver’s seat, that would be a good use of his skills. But taking the helm of some new quasi-government entity? We should bristle and so, I imagine, would he.
