From the definitely not co-ordinating with Stephen Colbert Americans for a Better Tomorrow, Tomorrow SuperPAC, a negative ad attacking the negative ads of the Republican frontrunners… then vows donations will be used to “destroy both these guys and their SuperPACs with a merciless ad torn so fierce they’ll wish they’d never been incorporated… an orgy of pure distortion leaving nothing behind – but the clean campaign we all deserve.”
You might very well think that…

If anyone doubts whether Colbert leans left or right, just remember he gave his superPAC money to Jon Stewart. I was just speaking with someone who thinks Colbert is a secret Republican and confronted her with this. She couldn’t explain it, but her belief didn’t waver. I stood there acting smug and not surprised, because I really was both.
It’s hard to say what Colbert’s “true” political beliefs are behind his artful façade of being an willfully obtuse, right-wing blowhard. As long as his targets are fairly indiscriminate, I can’t see that it really matters.
