The Root of Liberal Humor?

This bit in Jay Nordlinger's latest Impromptus brought to mind Marc's recent comment that liberals do better at comedy:

And I am reminded of one of the reasons I fled the Left, many years ago: Personally, they were so mean — so nasty, so indecent. So full of mockery, ridicule, and scorn. I had to ask, "If the Left is the party of love and compassion, how come so many of them are such a**holes?"

We're talking generalities, here, of course. For one disclaimer, I'm not suggesting that I don't have my (ahem) liberal moments. It's at least arguable, however, that "mockery, ridicule, and scorn" are key spices in the comedic recipe and that Nordlinger's observation is not entirely without basis.

Since we're also talking impressions, rather than evidence, it occurs to me that perhaps the most unmean comedian of the last fifty years, Bill Cosby, has been making news for the past few of those years for his conservative-esque racial statements. Of course, Dennis Miller comes to mind as contrary evidence, although he's more of a libertarian (and for that, I need another "ahem").
