The liberal blogger who put together this video, a Clinton supporter at the prominent left-wing site MyDD, darkly warned:

If we choose Obama as our nominee, we are locked-in to this narrative. There is no going back, no bogus NBC polls to save the day. No Anderson Cooper softball interviews or phony charges of racism that will rescue us.

The opponent doesn't care. All the thoughtfulness and restraint of a Democratic adversary will be gone.

Yes, the thoughtfulness and restraint of Clinton and her supporters have historically been very impressive. Once Obama has to deal with those Republicans, who will do anything to win, God knows what will happen.
