Here is a comment from a closely related thread:
When a hefty fraction of the public thinks Tucker Carlson is a source of Truth, it’s hardly surprising that same hefty fraction totally thinks Trump is the ideal person to Make America Great Again. Especially white badly educated America.
For a very large fraction of the country we do not have politics about policies and priorities. Instead we have reality TV culture wars. And folks are voting for which reality TV character they want to win the culture war on their behalf.
