From Steve Benen at Political Animal:

What Race is Brokaw Watching?

...

I've been working on a project during the campaign, chronicling John McCain's flip-flops. As of now, the grand total stands at 74 reversals, but just as importantly, the vast majority of the reversals were part of a coordinated effort to reinvent McCain in order to shamelessly pander to the Republican base, abandoning nearly all of the positions that people like Brokaw admired so much eight years ago.

As Kevin noted, "It's not just that McCain has changed a lot of his positions, it's the fact that he's so plainly changed them purely for the sake of political expediency."

Quite right. In order to con Republican voters into supporting his campaign, McCain reversed course on practically every pillar of the GOP policy agenda, including taxes, energy, the role of social conservatives, gun control, abortion rights, and immigration. No presidential nominee in modern U.S. political history has reinvented himself more than John McCain.

Of course, if McCain has Brokaw fooled, and Brokaw is a veteran journalist and the host of "Meet the Press," imagine how easy it is for McCain to con the typical American voter who doesn't have time to pay attention to the ins and outs of politics.
