Biden looks like a spent force. Physically he looks tired, displays an impotent rage, a mere ghost of his former self, looks shriveled & diminutive, doesn't show a fighting spirit.
Warren is hitting her stride, with vigor, passion and on message. I've never seen Biden hit hard on Trump's corruption. Biden looks like male version of Hillary. Where's the sense of outrage?
I wont be surprised if Warren became D's nominee.
