Billmon sums it up about Colbert's performance at the correspondent's dinner:

The underlying message, never stated or even acknowledged, is that there are no disputes that can't be resolved within the cozy confines of our "democratic" (oligarchic) system. Friends don't send friends to jail -- or smash their presses or abolish their political parties or line them up against the wall and shoot them.

Read the whole post. It's excellent.
