President Trump revealed many things. The most important in my view were the Rinos and Deep state.

Have you seen the film Moneyball. A great scene near the end where the owner of the Red Sox says to Billy Beane that the establishment hates those who come up with a fresh and/or better way to do things. When he says this, it reminded me of President Trump. They all hated him - the media, the Democrats, and especially the RINOS and even conservatives. He was not playing the game the way it was supposed to be played.
