At least four top House Democrats have privately called for Biden to step aside.
Biden really thinks he can keep the rank and file in line. He's banking on it. In that interview with Stephanopoulos he pretty much dared them to say something. I can't imagine much will change in his mind until these folks grow a pair of cojones and start going public. With them all back from recess, this next week will be very telling.
