We don't have to "sell" you on anything! It's YOUR responsibility to face the reality of it all and decide for yourselves. Trump SHALL be the nominee. So you either vote for him, or help Hillary or Bernie or Biden, or whomever win; or not.
Most of the bernie supporters will NOT vote for Hillary.
Many of the Dem base don't like either and have already come over to be Trump supporters.
So you want to play DOG IN THE MANGER/CUT OFF YOUR NOSE TO SPITE YOUR FACE, do you? You are with us, or against us; it's up to YOU.
I already said who I would vote for. Don’t need a sermon.
