Quite true. If there had been a real Democratic Convention, the Sanders supporters would have held some loud demonstrations and would have nominated him for president. Chances are he would have gotten up, thanked them, declined the endorsement and called for party unity since Biden has embraced significant portions of his politics.
Let’s hope that this is a sign that many Sanders supporters will not vote. They have been railroaded twice with respect to the presidential nomination. They might not be a majority of the party, but they are the loudest, most active and enthusiastic. Nobody is enthusiastic about Joe Biden. He is just a placeholder for most Trump hating Democrats. The ballot may as well read, “Trump … the other guy” for most Democrats. The “other guy” could be Mickey Mouse or Donald Duck.
