I will risk making a prediction. A sad one by the way. I think I figured out Trump's strategy: He will sign executive orders related to his 4 or 5 campaign talking points. He will then sit back and spend the rest of his term fighting all the challenges to those executive orders and saying "I am doing the right thing and see all those elites fighting me".
He will control the narrative and get the public opinion of the "little guy" on his side. He does not need to demonstrate or achieve anything substantial on the economic front. Just saying that there is no progress because he is being blocked will rally the troupes to give him another 4 years.
What he will achieve is increase the anti-minorities sentiment and that will be his true legacy.
