Over at Salon, Glenn Greenwald has a spirited, link-rich argument that "the GOP is once again donning their libertarian, limited-government masks in order to re-invent itself and, more important, to co-opt the energy and passion of the Ron-Paul-faction that spawned and sustains the 'tea party' movement." Excerpt, with the links excluded (too many!):
The Party that spat contempt at Paul during the Bush years and was diametrically opposed to most of his platform now pretends to share his views. Standard-issue Republicans and Ron Paul libertarians are as incompatible as two factions can be—recall that the most celebrated right-wing moment of the 2008 presidential campaign was when Rudy Giuliani all but accused Paul of being an America-hating Terrorist-lover for daring to suggest that America's conduct might contribute to Islamic radicalism […]
This is what Republicans always do. When in power, they massively expand the power of the state in every realm. Deficit spending and the national debt skyrocket. The National Security State is bloated beyond description through wars and occupations, while no limits are tolerated on the Surveillance State. Then, when out of power, they suddenly pretend to re-discover their "small government principles." The very same Republicans who spent the 1990s vehemently opposing Bill Clinton's Terrorism-justified attempts to expand government surveillance and executive authority then, once in power, presided over the largest expansion in history of those very same powers. The last eight years of Republican rule was characterized by nothing other than endlessly expanded government power, even as they insisted—both before they were empowered and again now—that they are the standard-bearers of government restraint.

But that GOP limited government rhetoric is simply never matched by that Party's conduct, especially when they wield power. The very idea that a political party dominated by neocons, warmongers, surveillance fetishists, and privacy-hating social conservatives will be a party of "limited government" is absurd on its face. There literally is no myth more transparent than the Republican Party's claim to believe in restrained government power. For that reason, it's only a matter of time before the fundamental incompatibility of the "tea party movement" and the political party cynically exploiting it is exposed.
