Yep. This is part of the "close the deal" template. He was saddled with the personality of "Trump the actor" from his time on Apprentice and in the public eye. He had to start there, that is what people knew. But he couldn't stay there and win the election, hence a transformation over the past few months. Not sudden, a little bit each day. It is important that the people see him as genuine, not acting, not scripted.
True. He no longer fits the image the left tried to create for him.
One new thing. He says he will stop giving billions of dollars to the UN for climate change issues and instead use those billions to clean up our water and fix our own American environmental infrastructure.
