The fact that conservatives are afraid to acknowledge is that a lot of the "base," or the primary voters, aren't nearly as conservative as we'd like.
OR . . . they're malleable, but need a national conservative message/leader to energize them. But while I think conservatism is alive and well, I also am disturbed by the very fact that McCain had little competition in most states, and that the so-called "conservatives" like Hunter, Brownback, and Thompson, got KILLED.
