Well duh! He was never a Democrat and I always questioned how the powers that be at the DNC could/would allow him to campaign for the Democratic nomination.
The only thing I can figure is that they, like everyone else anticipated Hillary being indicted and they wanted SOMEONE with a smidgen of name recognition to fill the vacuum that would have been created.
So Bernie has taken his ball and gone back to the Senate where he will once again be the taken for granted Socialist in the room.
At least he had his 15 minutes of fame and impact, tho temporary, on the formulation of the Democratic platform, which Hillary is already “Changing” back away from now that she has won the nomination.
Wonder what the NEXT scandal she will have to ask “what does it matter” about will be?
