Lots of folks are feeling he pinch. Every day the average american spends 100 dollars. That is 800k people out. Forgetting the multiplier effect, that is a lot of money lost to the economy daily. And there are another few hundred thousands of people who cannot get their business done.This effect has to show up somwhere.
It will last as long as the Mad Hatter wants it to, or unless the GOP senators realize that they will be voted out in 2020. Trump operates in an alternate universe so reasoning with him is a wasted exercise.
The economy is slowing because of the Feds. He will add Pelosi to the list. The farmers are screaming because the federal support that they get is delayed. Of course they are the ones who rant that they dont need Big Gov't.
The GOP will do badly in the farm belt.
