 Elizabeth Warren is like 75, 76. She's on her game. Joe Biden isn't, noticeably so. It's evident to everyone. The schedule that he keeps, 10 to 4, nothing before 10 a.m., nothing after 4 p.m. This absurd inside joke among the White House staff, Operation Bubble Wrap is what they call it, that they surround him, make sure he doesn't fall, he doesn't have a senior moment. It's ridiculous.
