I was disappointed to read today that if Bernie does not win, he says he...

...will not endorse Hillary unless she gets on board with with certain parts of HIS beliefs and platform.
This makes him seem more like a third party candidate and not a true democrat if he refuses to endorse the winner unless he gets his way. Please don't let us go back to the days of Ross Perot and Ralph Nader and end up with a Trump or Cruz presidency.
That is just my take on his comment.
