Molly Ivins has an idea which isn’t bad at all.

Here’s some background on Bill Moyers.

UPDATE:  Ezra Klein agrees:

I’ve always found Moyers writings and speeches to be closer to prayers than essays, appeals to our better angels rather than for our grudging votes. When I’m depressed with the state of the country or feel overtaken by the enmities rather than the values that animate politics, I crack open Moyers on America to refresh my perspective. I would love to see him run, the race could truly benefit from a conscience candidate. And so, incidentally, could the country.
