I respectfully disagree.  Between Chris Matthews, Vann Jones, James Carville, and Brian Williams (to name a few), they are sounding the alarm for the need to stop Bernie now and a 'moderate' prevail in the primary. I believe it's already too late: they are painted indelibly by their socialist leanings.    A brokered convention will not bode well for their Fall elections.  The ugly face of the radicals will emerge so prominently that Democrats will not be able to separate themselves from those bomb-throwers who will be trashing Milwaukee and every other city they have enough 'brown shirts' in to cause a riot if they perceive Bernie is 'cheated' again.  Other than other bomb-throwers, who is going to vote for that shit?
