Maddow does an interesting job for one of these interviews -- rather than give Mr. Huelskamp just a platform to vent, she refuses to let his most hyperbolic statements go without challenge, and keeps trying to get him to be specific, and she is as blunt, though polite, as I've seen an interviewer. And at times her reaction ranges from anger to wanting to burst out laughing from bemusement.
I was watching the interview live, and unfortunately this video is the interview alone, not the discussion after. Half the fun of that discussion was seeing the reaction of the other panelists, seemingly pleased that they hadn't had to handle the interview themselves, and understanding the trapeze act Ms. Maddow had had to go through live. The best reaction came, however, from Chris Hayes, who had sat quietly during the others' comments, and then suddenly just interrupted, ready to burst, unable to hold his almost-sputtering reaction. To paraphrase him, he said, struggling to stay seated, "There in a nutshell we have the past five years of politics in Washington. The president makes a speech about raising the minimum wage, saying we should get business leaders together, and how wonderful America is, and the Republican response is, 'What about all the people killed at Benghazi??!!!'"!!!!!
