Slow-Mo Creepy Uncle Joe is just going through the motions of being a presidential candidate without any real desire or zeal. He’s being paid handsomely to keep the seat warm for someone else.
That’s what I think too, Biden is just a placeholder, for a “player to be named later”, as they say in baseball.
At the 11th hour he'll be "incapacitated" somehow and either Michael, or Skankles will appear to save the day.
