What did Donald Trump do today?

He said replacing NAFTA with something very similar was his main reason for being president.

Trump visited Michigan today, a state he desperately needs to win in November if he is to be re-elected and prolong his temporary immunity from prosecution. He spoke about the USMCA, the replacement (or at least renaming) of the North American Free Trade Agreement (NAFTA). Trump called it "probably the number 1 reason that I decided to lead this crazy life that I’m leading right now."

Even allowing for normal standards of political exaggeration, though, this doesn't really make sense. The USMCA is, by all accounts, virtually the same thing overall as NAFTA. Much of what is different was put in not by Trump but by House Democrats—so much so that the Republican-controlled Senate tried to stall it. 

Most importantly to Michigan voters, the USMCA is not expected to have any real effects on the deepening recession in the manufacturing sector.

Why does this matter?
