Last week, former Republican Congressman Joe Scarborough denounced Glenn Beck:

SCARBOROUGH: You cannot say that the president of the United States, Mike Barnicle, hates all white people. You cannot call the president of the United States a racist. You cannot wallow in conspiracy theories as he did for about a month, suggesting that FEMA might be setting up concentration camps and going on Fox & Friends and saying, “I can't disprove it,” and then wait a month. You can't stir up that type of hatred -- calling the president a racist.

...

I know how these stories end. I always know how they end -- and I'm talking to you Mitt Romney, and I'm talking to anybody who wants to be president in 2012. You need to call out this type of hatred, because it always blows up in your face.

Now that Scarborough has discovered the danger of the far-right extremism on display on Fox News, maybe it's time he apologize to Paul Krugman?

See, back in June, Krugman wrote that “right-wing extremism is being systematically fed by the conservative media and political establishment” and went on to state that “the likes of Fox News and the R.N.C. ... have gone out of their way to provide a platform for conspiracy theories and apocalyptic rhetoric, just as they did the last time a Democrat held the White House.”

That led Scarborough to lash out: “Paul Krugman, like a lot of I would say extremists on the right, they only see their side. They have a close-minded worldview.”

Well, Scarborough's comments last week look an awful lot like Krugman's from June, don't they?

Come to think of it, this would probably be a good time for Scarborough to apologize for his misinformation about that DHS report on far-right extremists, too.
