Democratic Primaries

In '16, Bernie had, and exploited to his advantage, the benefit of doubt. Coming to the convention, he claimed he would bring new voters to the General election. He pledged support for the Democratic Party. He even implied that he will remain registered as a Democrat past the elections. None of it materialized. He dropped the "D" label as soon as it became convenient, His demands for changes in the Democratic platform were met without the promised reciprocity on his part, his new votes never showed up to vote for Hillary in any meaningful numbers. It was a serious miscalculation on the part of the DNC to take Bernie's promises so seriously.

Bernie no longer has this benefit of doubt. His position within the Democratic party apparatus is much weaker today, not in the least because he keeps attacking the party and its members. His word is not worth what it used to in '16. Even his position within his movement is not what it used to be: the extreme radicals coddled by Bernie are sensing his weakness, and slowly but surely taking over, thus irreparably damaging the movement in the process. Bernie doesn't appear to be able or willing to control them any longer. His political career is nearing its end.

Time, and the Democratic Party along with it, is moving past Bernie. He only has months of relative credibility left, and he is wasting it as if there is no tomorrow. If he goes on like this he will completely discredit himself by the time of the Convention.
