There were many points Trump could have made if he would have calmed down. As an example, Biden claimed his family was off limits. NOT TRUE, when Hunter Biden interjects himself into governmental policy with Ukraine and China, it is NOT off limits. Then what about Solyndra and the Obama Biden involvement? So much was left on the table.
You're talking about additional specific points Trump could have said. That's a substance issue, not the "form" issue--that of "interrupting" or being a meanie-head--that you seemed to be citing before.
Those points can be made in campaign ads. All of our debaters always miss points they could have made. I often sit there thinking I'd be a better debater because I'd include all these esoteric points.
