What we learned from today's Radar profile of lunatic presidential candidate Mike Gravel:

* Mike Gravel is a bad driver.

* "All I know is that if I can get up to double digits, it's Katie bar the door!" He claps his hands together and smiles a Chosen One smile.

* Tom Edsall is actually insane: "David Broder is the voice of the people," he replies matter-of-factly. Gravel starts to smile, assuming Edsall is making an absurdist joke. But Edsall is not joking. The two men look at each other in awkward silence over a great gulf of unshared beliefs, then Gravel chuckles and walks ahead into the restaurant.

* "Gra-VEL"
