Bernie Sanders QUITS, Supporters Declare WAR On Democrats As Trump Calls On Them To Join Republicans. Bernie Sanders has officially ended his campaign for the President of the United States of America. He has conceded that he would not be able to defeat Joe Biden and would thus suspend his campaign. But many of his supporters, progressives and far leftists, are livid. They are furious that even though Joe Biden is not viable the DNC and Democratic establishment supported him to run against Trump. Trump will absolutely crush Biden and everyone knows it. For what reason did Democrats think he would be a good idea? Perhaps the Democrats just don't want an outsider like Bernie to take the reigns of the party.
