especially since he already committed to another debate.
It’s actually the opposite problem. There’s wasn’t going to be another debate for Biden to potentially redeem himself. Trump wasn’t going to do with another debate with him to give him that chance, why would he? He didn’t debate anyone in the primaries, because he didn’t need to. He wasn’t going to give Biden a chance to prove “it was just a bad night.”
But with Harris as the candidate, Trump has to do another debate or he’ll look weak. In the next debate Trump will look like the guy that’s too old. Which he is, just didn’t look that way next to Biden.
