Have not seen any fake news surveys, but my guess is that MANY union guys voted for Trump.
1-Political talk was low...DURING an election year.
2-NO ONE really had anything positive to say about Hillary.
3-Some people ACTUALLY talked well of Trump.
4-The OFFICIAL Local input of the election seemed almost nil.
I have NEVER seen a presidential election where the Local and the guys were so...unenthused. Look at Michigan and Pennsylvania.
Autoworkers union and auto suppliers that are union, in Michigan. And Steel workers and coal miners in Pennsylvania. Plus the industries in Ohio. ALL these states went Trump.
At the very least, a lot of union workers stayed home.
