Trump was very satisfied with the election debate, but some allies, donors and advisers shook their heads and smiled bitterly. Why?

Some Republican officials, donors and advisers said that Trump messed up the debate with Harris, but Trump himself thought it was one of his better or even best debates. Who is right?

Republican Senator Lindsey Graham, as an ally of Trump and one of the few party leaders who publicly said that Trump performed poorly, said that Trump "missed the opportunity" and that Trump lost the opportunity to promote his achievements because he failed to focus. Is his view objective?

Six Republican donors and three Trump advisers believe that Harris won the debate mainly because Trump was inconsistent. Does this statement make sense?
