It was a rough Tuesday for Joe Biden. Someone at the White House must have forgotten to mash up the donepezil in his rice pudding. It's always good to give him a double dose when Biden has a day's worth of events where he's going to be out in the public. It's also a bad idea to schedule a day's worth of events where Joe Biden is going to be out in the public. But sometimes the White House just has to say YOLO and hope he doesn't embarrass himself like he did at the G7.
As far as Joe Biden looking like a confused old coot goes, Tuesday wasn't the worst we've seen him. He didn't lash out at a reporter or (allegedly) tell them that his butt's been wiped. He still had some noodle-scratching moments. Like claiming people don't call tornadoes "tornadoes" any more.
