I think Bernie waited too long to do this — the fact that he is (finally) endorsing Hillary is irrelevant now.  There are, to be sure, some very loud and obnoxious #BernieorBust supporters who are actually butt hurt by this, having held on to the delusion for so long.  It is unclear who they will take it out on, Bernie or Hillary… but it hardly matters.  I don’t think very many of them will go to Trump.

Trump apparently hoped it would be so, and is now calling Bernie a “sellout”

… and I really don’t think that will help him get Sanders supporters votes.

Bernie explained WHY he supported Hillary, and not Trump.  Hardly a mystery.

UPDATE:  Now Trump is trying to use carrots:

To all the Bernie voters who want to stop bad trade deals & global special interests, we welcome you with open arms. People first.

I’m no expert but Trump better worry about getting Mitt Romney voters before Bernie Sanders’ voters.
