He can hold over his base for so long with media attacks and nativist immigration rhetoric before they get restless. I have read about a factory in IN shutting down and jobs shipped to Mexico and nothing from Trump and coal plant closing in OH/AZ. At some point parts of his base will realize he is not delivering for them.
The news sites that cater to his base and Fox will likely just blame liberals for nothing happening. They won't understand that Republicans control Congress as well and can do what they want so they can pull the wool far over their eyes.
