I listened to it on the car radio, but I think I must have been listening to a different debate.
Trump highlighted his refusal to cooperate with Iran and correctly pointed out that Iran did not have the dollars to support their proxies while he was President. He cited his withdrawal from the Paris Accords as a policy success and pointed out inflation did not make its move until Joe was President. He continuously pointed out differences (and the results) in policy between the two. Afghanistan was a biggie; Trump seemed positively angry that Joe screwed that pooch worse than anything else he did.
Overall, Trump was much stronger on policy and Joe forever cited misleading statistics that everyone knows are weak substitutes for the truth.

Everyone should just accept that Joe is close to being an invalid. He still makes policy decisions and certainly understands the ramifications. He still has Susan Rice and Obama at his side, so a second term will look a lot like his first term.
Why is everyone surprised that he is kind of a lame character? That has not changed!
It is kind of late for the Dems to decide to abandon their candidate. He embodies their world view, and he HAS the nomination; they do not.
