No a loss because Bernie needs all the delegates he can get. Getting only half in a state that he should have won hands down like Vermont is serious.
Obama got pummeled by Hilary way worse and he was seen as the more liberal alternative to Hilary then.
Bernie did MUCH better than Obama did. Your predictions thus far have all been wrong. The other day you said it would be over. Its FAR from over. You will see that Bernie wins all the swing states and the big delegate states. Like I said, Hilary only loses support whereas Bernie only gains. Bernie will NEVER lose support, Hilary is continually losing support.
Its going to happen and you are going to have to accept it.
