Ol' Joe will clean the blowhard's clock, especially with the mic mute. Hell, even without the mic mute last time...Joe won. Especially when he shut Trump down with...'Will you shut up man? This is SO un-presidential'.
Sure Joe stutters a bit, but he has a good vocabulary and delivery. He can talk issues, form coherent and meaningful sentences, stick to reality, is intelligent and sounds presidential. Trump possesses none of these rudimentary abilities. Trump is a buffoon.
