Conservative David Frum is interviewed by Bill Moyers and has this to say about the radio talkshow conservatives like Rush Limbaugh:
BILL MOYERS: You describe yourself as a calm conservative. But you have certainly aroused those to your right in the Republican Party. You know, talk show hosts like Mark Levin have come after you saying you're kneecapping your own. What about that?
DAVID FRUM: Look, a lot of the conservative movement in this country is conducting itself in a way that is tremendously destructive. Both of the basic constitutional compact of the requirements of good faith and of their own good sense. I mean, when you were going on the air and calling the President of the United States a Nazi as Rush Limbaugh has repeatedly done. When Mark Levin -- you mentioned him -- he said the President of the United States is literally at war with the American people. And then people begin, unsurprisingly, showing up at rallies with guns. Well, obviously, if the President were-- I mean, folks, if I believed the President of the United States were a Nazi, were planning a Fascist takeover, it would be contemptibly cowardly of me not to do everything in my power, including contemplating violence, to resist such a thing. Every decent person should do that. That's why you don't say it when it's not true. And I mean, one of the ways that the constitutional system works is with some understanding that the people on the other side have slightly different priorities but they share your constitutional values. They have invested in the same system. The problems they've got are hard problems. And even if you don't like their answers, you have to have some restraint in the way you talk about them, as you would hope they would have about you. And I think it's just outrageous. It is dangerous. It's dangerous for the whole constitutional system. Now, I'm absolutely prepared to fight with them. And by the way, it's dangerous to conservatives because the effect of the talk of people like Levin and Rush Limbaugh is to kill our cause with voters who are under 65. You make that man the face and you say let us contrast him to Barack Obama who is maybe too expensive but who seems calm and judicious? That's an ugly comparison.
