Actually, he DOES have the skills. He has the "gift of gab", and has mastered a debate technique called the GISH GALLOP.
Basically, it involves spewing lies so fast people like me, who try to correct that shit, have their FUCKING HANDS FULL, to the point that the onslaught of lies are coming to fast and furious to cope with.
THIS IS WHAT TRUMP DID IN THE DEBATE.
One of the reasons Biden looked the way he did, is that he was dumbfounded by the steady stream of DEMONSTRABLY FALSE LIES, going unchallenged by the "moderators".
THIS IS WHAT HE ALWAYS DOES.
GOOLE IT: the GISH GALLOP.
