Brink Lindsey:

By the waning years of the Bush administration, the old "fusionist" alliance between libertarians and social conservatives seemed to be on its last legs. After the inglorious collapse of Social Security reform, the political agenda of the right was more or less free of any contamination by libertarian ideas. The GOP sank into ruling-party decadence marked by borrow-and-spend fiscal incontinence and K Street Project cronyism. The broader conservative movement, meanwhile, expended its energy on gay-bashing, anti-immigrant hysteria, fantasies of World War IV, meddling in the Schiavo family tragedy, and redefining patriotism as enthusiasm for mass surveillance and torture.

Now, however, opposition to Barack Obama and the Democratic Congress has sparked a resurgence of libertarian rhetoric on the right, most prominently in the "Tea Party" protests that have erupted over the past year. "Libertarian sentiment has finally gone mainstream," wrote Chris Stirewalt, political editor of the conservative Washington Examiner, in a column this April. "After two wars, a $12 trillion debt, a financial crisis and the most politically tone-deaf president in modern history, Americans may have finally given up on big government."

Such talk gets many libertarians excited. Could a revival of small-government conservatism really be at hand? After the long apostasy of Bush père et fils, could the right really be returning to the old-time religion of Goldwater and Reagan? Could the withered fusionist alliance of libertarians and conservatives channel today's popular disgust with statist excess into revitalized momentum for limited-government reform?

In a word, no. Without a doubt, libertarians should be happy that the Democrats' power grabs have met with such vociferous opposition. Anything that can stop this dash toward dirigisme, or at least slow it down, is a good thing. Seldom has there been a better time to stand athwart history and yell "Stop!" So we should rejoice that at least some conservatives haven't forgotten their signature move.

That, however, is about all the contemporary right is good for. It is capable of checking at least some of the left's excesses, and thank goodness for that. But a clear-eyed look at conservatism as a whole reveals a political movement with no realistic potential for advancing individual freedom. The contemporary right is so deeply under the sway of its most illiberal impulses that they now define what it means to be a conservative.
