As we all know, there is a high probability that Creepy Joe will have a stroke before the election takes place. That is the number one reason he will not go out on the election trail or face Trump in more than 3 debates. His health is at peril. He is not healthy at all. He's been sick for a long time.
So if/when he has his debilitating stroke, who then runs for the Dems?
If that were to happen it would be a walkover, and we're having Trump for another term.
(Only a severe write-in campaign from the Dems on ONE person would have a chance to dethrone Mr. Incumbent)
