Josh Marshall nails it:
As you see, the RNC has now expelled NBC News from the Republican debate schedule. If I don't say so myself, I think my comparison to the Boehner drama was more prescient than I realized. There has to be someone betraying them or some new outrage to feed the machine. With Obama fading into history, with the 'establishment's' candidate vanquished, now it's NBC News. You get a sense of where this is going that Ted Cruz says that Limbaugh or Hannity should moderate the debates. To be clear, this isn't about whether the debate was good or bad or whether axing NBC is fair or not. (I said the debate was a mess while it was happening.) In the grandest sense, who cares? It's just that the entire drama and whine-a-thon is ridiculous. This is their new big issue? Like I said, the outrage needs a target. Who's betraying them now. The pattern takes over everything.
