Come 2008, there was a brief moment of introspection. National Review hosted its "whither conservatism" conference at a Washington, D.C., hotel. Right-leaning intellectuals began dreaming up new journals, Web magazines and blogs to play a part in reshaping the coalition's future. All the old fault lines reemerged. Did the GOP need to end its experiment with "compassionate conservatism" and return to advocating smaller government? Did it need to better address the needs of the working class? Did it need to become more conservative or to moderate?

These were all questions of consequence.

But the American right was incapable of adjudicating them. It didn't matter that Reihan Salam and Ross Douthat wrote a very smart book setting forth one possible political program; that David Frum engaged in the same process; that Bruce Bartlett pressed fiscal conservatives to reexamine their failures; that Matt Welch, Nick Gillespie, and their Reason staffers weighed in with sharp libertarian critiques; that figures from Ron Paul to Daniel Larison offered devastating eviscerations of neoconservatism; that Tim Carney attacked the right's penchant for corporate cronyism; or even that the Tea Party grew into a populist force as the Obama Administration began.

Ideally, the right would find a way to incorporate nuggets from all these critiques. Sure, their advocates want to take the Republican Party in dramatically different directions. Winners and losers are inevitable.

But respect for empiricism and reasoned, intellectually honest debate could ensure that the best critiques would be aired; the best ideas attempted; and the very worst rejected, whatever their provenance. At minimum, it's possible to imagine a coalition where sound argument was valued enough to render the most vile ad hominem and the most hair-trigger heretic-shaming beyond the pale. Instead Rush Limbaugh and Erick Erickson remain among the right's most influential voices. Fox News is movement conservatism's go-to information source; its big boss, Roger Ailes, profited from airing lunatic conspiracy theories from Glenn Beck that no one can defend, but he hasn't been discredited. And that's just the realm of AM radio and cable television.

Think about conservative magazines.

National Review's readers have been exposed to the argument that President Obama is allied with our Islamist enemy in a "Grand Jihad" against America; in Forbes, Dinesh D'Souza set forth the thesis that Obama's every action is explained by a Kenyan anti-colonial ideology that overwhelms all else. I mention those magazines not because they're worthless, but because both publish good stuff, and employ a lot of talented people who are more than smart enough to see through this nonsense. An ideological movement that prided itself on openness to all ideas could be forgiven for the most laughable that made it onto the pages of marquee magazines, but on the right, this madness gets published in venues where David Frum is deemed beyond the pale.
