If done the correct way, I suspect this move will be seen as "smart" by his base, he just has to word it the right way.
I genuinely believe Trump's base could care less for results. Trump could not change anything and if the economy is still good in 2020...they would enthusiastically vote for him again.
All Trump has to do is lie and his base will believe him
I wonder what possible gain they get out of this? They're bound to take off the rose-colored glasses sooner or later when nothing of consequence that benefits them ever happens.
