Why?
Biden (1) collapsed at the very beginning in his refusal to answer questions, (2) obfuscated and rambled the rest of the way through, (3) Trump was clearly debating two people, both of whom were distorting and lying.
Is your position that because Trump spoke forcefully and interrupted his opponents that he harmed himself? Do you have any evidence that regular people even worry about that sort of thing? These same criticisms were leveled at Trump during the Hillary debates. Trump won Blue States that same election year.
