On MSNBC’s “Morning Joe” this morning, host Joe Scarborough delivered a scathing rant against Glenn Beck. According to Scarborough, Glenn is “losing it before our eyes” and is “bad for the conservative movement.”

“He’s bad for the Republican party. He’s bad for Fox News. It’s that simple,” Scarborough said, referring specifically to Glenn’s recent work to uncover the socialists, progressives, and unions behind the unrest in Egypt and Wisconsin.

Guest commentator Pat Buchanan added that Republicans have a “responsibility and a duty” to make sure Beck isn’t speaking for conservatives.

Scarborough refers to a recent blog post by conservative writer Peter Wehner calling Glenn, “The most disturbing personality on cable television.”  I talk to Pete from time to time and have a good deal of respect for his analysis most of the time.  I found his most recent posts on Glenn, however, to be pretty shallow. It’s a popular sport to make dramatic denunciations of Beck themes without really engaging in a discussion of the arguments.

I’ve been involved in mainstream conservative thought and politics for 25 years and I can assure you that Wehner and Scarborough are mounting a very weak case.  I’ve worked with many top conservative leaders and politicians.  Glenn is about as thoughtful and sincere in his approach to political argument as anyone I’ve met. The depth and range of discussion around the Mercury and Blaze offices is the most interesting and electrifying of any place I’ve worked.

This weekend I’ll be posting a more thorough response to the Wehner/Scarborough arguments.  For now, watch the clip and help kick start my weekend response in the comments!
