Where am I denying anything? Two contradictory statements were made. One stating Michigan union workers were always Democrats and one stating most were right-wing deplorables. Elements of each of those statements can be true. I'm not familiar with Detroit car unions so I don't claim to know the answer.
I didn't say either, but do think Michigan union workers have been Democrats for decades until the 2016 election.
Both Left and Right have their deplorables: deplorable being defined as an anti-American asshole seeking to deprive Americans of their inalienable rights.
