Christopher Flannery has a lovely piece in The Claremont Review of Books on why the Left lacks an El Rushbo sort of their own. I can’t resist giving you the start of it, as long as you read the whole:
"In the past months, as the world and I were concentrating on more serious matters, our thousand-eyed media couldn’t help noticing, in a desultory way, a certain small sideshow. Compared to the events sweeping across the center stage of history, it seemed a bit like a lost sea-bird fluttering on the fringe of an armada, but perhaps you noticed it, too. I refer to the liberals’ increasingly desperate effort to discover or create a Rush Limbaugh of the Left. Hapless candidates for the job were trotted out, wealthy partisans forked up millions for the cause, and so on—the details fade mercifully with time. But one theme kept bobbing to the surface of the reportage and commentary. It came from friends as well as critics and neutral observers, if I remember, and it was not a deep insight, in itself. But it was suggestive. It caught the mind’s eye and invited at least a little more desultory attention.
What kept bobbing up was the observation that it is not much fun listening to liberals. Compared with the real El Rushbo—ever buoyant, larger than life, overflowing with conservative joie de vivre—the lefty pretenders appeared, to friend and foe alike, anemic, wan, somehow depressing. In a word, grim; even the professional comedians. The Left is not a barrel of laughs.
My own listening experience confirms this general truth and suggests a corollary: the lefter you go, the grimmer it gets. If my political ear has not deceived me, this is bad news for the Democrats, who have to tune to the far left of the FM dial and crank up the volume in order to reach their party’s activist core."
And then this march of logic: "Here, then, is the root cause of the Left’s chronic depression and the irresolvable problem at the core of the Democratic Party: America’s success is their failure. And here is the corresponding cause of the good humor and vitality of conservatives: So long as America succeeds, they cannot fail."
