The real problem is that Trump will sign anything that the Republicans in Congress put on his desk.

Since the 1980s they have sought total control of the federal government, but it was always denied.  Now they have it.

The Republicans will quickly eliminate every progressive law written since FDR was in office.  Say goodbye to Social Security, Medicare, the minimum wage, labor unions, equal pay for women,  the 1964 Civil Rights Act, Roe v Wade, and a host of other laws that people who voted for Trump take for granted and depend upon.  These laws will disappear and noting will take their place. 

The USA is about to become a vast experiment in extreme right wing philosophy.

Most of the people who voted for Trump will suffer economically.  They were warned, but they believed his lies.
