I have no doubt that rank and file teamsters and other blue collar union workers would endorse and vote for Trump.
However, the union leadership is almost universally leftists, as are both the leadership and rank-and-file members of the government, teacher, and services unions.
Trump doesn’t need the union leaders money or endorsements (in trade for supporting some of their goals) and should go over their heads and appeal to the patriotism and economic welfare of the blue collar workers themselves.
THAT’S a WINNING strategy.!
You must know some of those guys, as do I.
I concur.
