These are just what passed by here in the last few days. And they're not even DU or Obama or Daily KOS.

Yep, I heard that even our founder, Jim Jackson, has been labeled a crackpot.
But, I’m concerned that there is a crackpot gap between us and the left. Not only does the left have more crackpots than we do, but their crackpots are bigger. Troubling.
