It's increasingly obvious that what passes for a "Republican Establishment" these days is focused heavily on surrendering to the most immediate ideological impulses of Tea Party and conservative movement activists (who are in fact the very same people in many places) and then coopting them for the 2010 and 2012 campaign cycles. In attempting a takeover of the GOP, the hard right is in many respects pushing on an open door. The RNC chairman, supposedly a "moderate" of sorts, never misses an opportunity to identify himself with the Tea Party Movement. Sarah Palin, who was the party's vice presidential candidate in 2008, has called for a merger of the Movement and the GOP. Republican Sen. Jim DeMint has argued that they have already more or less merged.

In his piece Martin suggests that the longstanding Republican pedigree of Florida Tea Party hero Marco Rubio somehow proves the "establishment" is still in charge. I'd say it shows that "establishment" is in the process of rapidly surrendering to the "conservative coup" that Martin scoffs at. Charlie Crist, whom Rubio seems certain to trounce in a Republican Senate primary later this year, was without question a major "GOP establishment" figure just months ago, and Rubio was considered a nuisance candidate. Now he's the living symbol of a "purity test" being applied to Republicans by the "grassroots" to dramatic effect.

Yes, many Tea Party activists continue to shake their fists at the "Republican establishment," just like unambiguously Republican conservative activists have done for many decades, dating back to the Willkie Convention of 1940. But with some exceptions, they are choosing to operate politically almost exclusively through the GOP, to the "establishment's" delight.

The emerging reality is that the Tea Party activists are the shock troops in the final conquest of the Republican Party by the most hard-core elements of the conservative movement. It's apparent not just in Republican primaries, but in the remarkable ability of Republican politicians to repudiate as "socialism" many policy positions their party first developed and quite recently embraced (Mark Kirk's support for cap-and-trade would have been considered relatively uncontroversial just a few years ago). You can certainly root around and find a few exceptions to this trend, but they are few and far between. And the implicit assumption of Martin's piece--that the "adults" of the Republican "establishment" will once again tame the wild ideological beasts of their party--is actually dangerous.
