You will not convince migatards that they have made a mistake. First they will bury their head in the sand and pretend prices haven't gone up. Then, after reality bites them in the ass they will say it's actually good because tariffs inconvenience foreign countries they have been told to hate (Israel not included, btw).
Migatards would eat Trump's shit if that meant a liberal would have to smell their breath. They are fueled entirely by spite.
