Insult the base, trash the base, and pay lip service to the base only when it
suits his needs.
Fair enough. McCain doesn't give a damn about Christian conservatives, actively campaigns against corporate interests, and is no friend to the right-wing commentariat. If McCain didn't have to pay lip service to the right on immigration, taxes, and judges, he wouldn't give them the time of day.
But is the right-wing the "base" of the Republican Party? On the results of the Florida primary and the upcoming California, New York, and New Jersey primaries, the answer is probably a big "no." To date, the success of the McCain campaign is an indication that the right is in fact a minority in the Republican Party. The right might be an active minority, an influential minority, and probably even the dominant minority in the Republican Party.
But they still look like a minority and they look like a smaller minority with every McCain win.
