Carl Bernstein, Douglas Schoen, Robert Parry are all good sources for what's going on in Insider Washington. There are other recent indications that the Democratic establishment is circling the wagons (probably because they increasingly expect a fatal FBI report):
--Jerry Brown's panicky endorsement of a candidate; something he has never done this early
--Establishment heavyweights, Harry Reid and Diane Feinstein, saying Bernie should drop out
--Speculation that Sheepdog Elizabeth Warren will call for Bernie to drop out after California
--Obama in Indiana yesterday stumping for party unity against Trump
--Speculation that a Biden-Warren ticket would unite the party
In the June 7 primaries, Bernie will win the majority of states and at least break even in those states' delegate count. The Clinton embeds at MSNBC & CNN will 'officially' declare the race over and done.
Bernie will be in tall cotton. By then, he will have likely won 25 states and can sit back looking pretty for the next 7 weeks until the Democratic Convention July 25. In the meantime, Clinton will be sweating out an FBI deposition and then an FBI report that looks to be more ominous for her every day.
The DNC is already weighing the possibility of a Biden/Warren Hail Mary pass, but that just confirms the depth of their delusions.
Really, really looking good for Bernie Sanders chances.
