They'll argue over the moderators and networks, after which Biden will use that as an excuse to not show.
Look how Creepy Joe lost his shit with his own constituents
Q: Joe, what will you bring to the table as our candidate?
Joe: You're a lying, dog-faced pony soldier!
Trump is an instigator. He knows how to get under Joe's skin. The President is also very quick on his feet.
Trump has a functional brain. Obviously, if Biden were at an ADVANTAGE in getting before a national audience and promoting his position, demonstrating his contrasts with Trump, enumerating Trump's failings, and going toe to toe with him in a debate and giving him the smackdown, they would be ANXIOUS to put Joe up there!
You couldn't keep Joe away.
The Left: Absolutely SURE of an easy win over Trump, just not with the guy they got to run with.
2020 BALLOT:
X: - TRUMP
X: - NOT TRUMP (insert anonymous DNC candidate here)
