I'm pleasantly surprised at how non-partisan this is. I sort of figured it would somehow endorse Democrats or the left and/or be anti-Tea Party. Not so. In fact, it's almost apolitical.
Yeah, Jon isn't as "left leaning" as popular wisdom tells us he is. He may pound on the right more, but he certainly hits the left a lot too. Especially now that they have been in power and have failed at it (again).
I think that this is more a function of his being left of the Democratic Party than anything.
And that the rule-of-thumb for any left-leaning comedian seems to be that the Republicans are evil and the Democrats are incompetent.
