Not Since Hewitt-Sullivan ...

The Mark Levin-David Frum dust-up - on air no less - is a riveting example of two varieties of American conservatism colliding. You can listen to it here. David finishes his post thus:

As I hung up, I wondered what it would be like to be a new listener, a nonpolitical person, tuning in to Mark Levin’s show for the first time. The ferocious hatred and anger – the shouting at people not present to reply, the self-pitying complaints against a world that does not pay enough respect: it’s an ugly performance. Has Levin ever convinced any listener of anything that listener did not already believe? And of those who come to the show uncertain of what they believe - mustn't the vast majority come away from these rage-filled narcissistic tirades thinking, "If that's conservatism, I want no part of it"?

Alas, it is conservatism in America today. And, yes, I want no part of it.
