Conservatives and free marketers have many disagreements with McCain, and they're right to. McCain-Feingold, McCain-Lieberman, the votes against the Bush tax cuts -- these are not exactly small matters. But what he said today should get some attention from advocates of limited-government.
On earmarks, spending, taxes, and health care, McCain vowed to pursue a sturdy, realistic limited-government agenda.
