If Bernie has any balls; he would call out Biden on his sheer stupidity, criminality, pervertedness.
But Bernie doesn’t. He will attack Trump and make it a who hates Trump the most show; then get paid off again.
Bernie did the same thing when he was Hillary’s sparring partner 4 years ago. Hillary was such a weak candidate in the primaries that she almost lost to her own tomato can. Had Bernie wanted to (or had the instincts) he could have KO’ed Hillary at several points with all her scandals floating around in the News.
Same thing here. Joe Biden is presenting serious mental deficiencies. The media is studiously ignoring it, but the public is taking not. If Bernie were to make a debate issue of it, the Media could not longer ignore it.
But he won’t. I think Bernie’s job is to deny Joe the delegates needed to get the nomination on the 1st ballot so the DNC can select the nominee (read Nancy Pelosi’s pick). Bernie gets his place on Martha’s Vinyard and Joe gets to go to Shady Meadows to await the Reaper.
