Virginia Postrel on McCain:
McCain is an instinctive regulator who considers business a base pursuit. It doesn't help that the senator's personal connections with commerce are largely limited to a highly protected local industry (distributing beer) and outright corruption (the Charles Keating scandal). And he's every bit as moralistic as Hillary Clinton, our would-be national nanny. His first response to something he doesn't like--particularly something commercial he doesn't like--is to ban it. The most extreme, and effective, case of this instinct was his holy war against ultimate fighting, a peculiar cause for a boxing fan and one McCain took up when he was still in his "conservative" stage.
There is no candidate still in the race who actually believes the private sector is as noble and as important an arena as government or politics.
