What media bias?

Think about it. What is the No. 1 newspaper in America by circulation? Why, that would be The Wall Street Journal, a bastion of conservative values on its editorial pages and hardly a suspect when it comes to lefty news coverage. (Though it’s worth pointing out that the paper has published some very tough coverage of Mr. Romney.)

What about radio? Three of the top five radio broadcasters — Mr. Limbaugh, Sean Hannity and the recently departed Michael Savage — have outdrawn NPR’s morning and evening programs by a wide margin. In cable television, Fox News continues to pummel the competition.

Many Republicans see bias lurking in every live shot, but the growing hegemony of conservative voices makes manufacturing a partisan conspiracy a practical impossibility.

Let’s be fair. It’s not as if everyone who believes there is a liberal bias needs to be fitted for a tinfoil helmet. But the trope is losing traction, partly because there are many robust champions of the right, which gives conservatives the means to project their message far beyond the choir.
