Brooks has painted an unflattering portrait of the Tea Partiers, one they have earned in spades. They are becoming what Don Rumsfeld used to call the insurgents in Baghdad--"Dead-enders", folks who have no desire to negotiate, no ability to recognize incremental (and sizable) attainment of long sought after goals. The Tea Party is increasingly coming to mirror ideological libertarianism, interesting stuff to talk about in a dorm room but utterly incapable of serving as an actual approach to governing in anything but an autocracy.
As inconvenient as it is for Hammer and others, we live in a Democracy in which a sizable MAJORITY of the American public disagrees with the ideology of the Tea Party. Not a plurality, a MAJORITY. Not that there aren't wonderfully inspiring elements in that ideology, elements which have already shaped the debate in positive ways bound to put a spring in the step of any conservative. Far too many people disagree with far too much of what the Tea Party represents for its approach to be adopted in toto. Like "useful" libertarianism, Tea Party ideas will alloy with "country club" Republican ideas to form governing approaches that appeal to the "muddled middle", those who thought Mr. Obama gave a good speech but who now wonder whether there was any there, there. This alloyed Republican Party will be stronger and more successful at the ballot box than any singular Country Club or Tea Party approach would produce.
My advice to the Tea Party Dead-enders? Win first, then get cocky about your ideology. And by win, I mean win a big policy debate. And win it within the system, the system of public debate and legislative compromise. Join with the dreaded "Country Clubbers" to dramatically reduce the scope and whim of government. Show the American people what a new and idea-brimming Republican Party is all about. Take back the Senate. Defeat Barack Obama. Once we've reached this point, well then if the Tea Party wants to conduct a Stalinist purge of the David Brooks/Bryan McGrath wing of the party, so be it. I'll accept my fate.
UPDATE--here's a good interview with David Brooks from The Daily Caller in which he 'splains himself. Pretty straightforward stuff, from where I sit.
