The important thing that Trump needed to do was destroy enthusiasm. Because this primarily hits Dem votes. Trump doesn't need to preach policy, so long as his voters are scared by the boogeyman - and chuds always are. Biden needed to lay down promise and policy. The only voters that can be hooked in at this point are potential Dem voters who are looking for an excuse to go to the voting booth.

There was none.

Mostly Trump took advantage of Biden's memory and speach issues by constantly barraging and confusing Biden's points and policies. Look at the post debate polls. It worked.
