Reply #1: three explanations

1. Some people are not happy unless they're angry, and they look for excuses to be angry. Those people were attracted to DU as a place to complain about George Bush. Well Bush isn't here anymore and someone needs to fill the void. They will grab onto any negativity.

2. The media dwells on the negative, because negative is interesting, and interesting is the most important thing, because it maximizes viewership which maximizes profit. Perspective and nuance do not maximize profit. So the media fuels the negativity.

3. This was an ugly and long primary, and some people, who didn't support Obama, are trying to justify to themselves that they backed the "right" candidate, the "real" progressive and that the people who supported Obama were duped. It was made worse because of the strong presence of identity politics in the race.
