Biden not campaigning…says it all. They've given up all hope of him winning.
Imagine if POTUS just quit campaigning the last 10 days or so before election. What would his constituents say. Yeah, we're pretty sure he has this in the bag, but I imagine plenty of us would say, "Even if we think he has it in the bag, WTF?" We wouldn't want him to quit.
Biden's done, forever.
