post some links to you so called data or research
Of course some wealthy people voted for THE TRAITOR just like some wealthy people voted for Biden and vice versa
Look how many more total counties Trump won compared to Biden
Trump is a winner with small counties where there is obviously low income/productivity and very likely a majority of voters who predominately uneducated.
If you don't like the data then take it up with Brookings Institute and the data sources they referenced.
You are way over-generalizing. Here is some data:
Go to: New York Times extremely detailed map 2020 election (they usually let you look at their stuff a few times before they make you subscribe)
Now go down to South Florida and look at the well to do areas along the shore (Coral Gables, Pompano Beach, Boca Raton, Palm Beach: all Trump. Same will be true in wealthy areas in many other parts of country (e.g. Cincinnati, Indianapolis)
Now go to the wealthy North Shore suburbs of Chicago or suburbs in the Bay Area of CA, or Philadelphia suburbs: all Biden
Now go to low education Black areas: all Biden
I am not saying you are wrong: you are pointing out rural and small town White America for Trump. That is a huge factor, and the higher educated in those areas are probably just as likely to be Trump voters as the less educated.
All I am saying is that it is very complex and also dependent on the region (and also on race). A highly educated person in Boca Raton, or Indianapolis, or Laguna Niguel is apt to be a Trump voter, as is a highly educated person in any small town throughout the nation. A highly educated person in the north suburbs of Chicago or Philadelphia, a Biden voter. A less educated person in most urban minority areas a Biden voter. A less educated rural white person a Trump voter.
