It also depends on what sort of Union, and what part of the country they are in. Police and Fire Unions will vote for Republicans a lot more than the Private Sector Unions. Certain Union vocations are more prone to vote Republican than others.
Unions mostly don't care about all the Democrat social issues, they mainly support the party for what they see as their own economic self interest.
These "blue collar" Democrats are more likely to support Trump, especially if they see him as beating back foreign competition and bringing jobs back to America, or other things they see as in their own best interests.
The worst Unions are the public sector Unions that are not Police or Fire. Government Employees unions invariably vote Democrat.
“The worst Unions are the public sector Unions that are not Police or Fire. Government Employees unions invariably vote Democrat.”
I sort of mostly agree with that but not quite. I just finished 30 years with the DoD in one of 3 Navy depot level rework facilities. Where I was is largest employer in Fla (2500-3000 employees) but never gets recognized as such because it is public sector. Anyway a large majority of employees at all 3 deppts are military retirees, vetrans etc. and I’m pretty sure many are as conservative as we are and vote accordingly. I agree though, never had much use for unions, especially in government work. They tend to make it even more difficult than it already is to weed out the dead wood and employ quality workers. Having said all that federal workers get painted with a broad brush here on FR as useless parasites of the system. I agree there is that but the people that I worked with are for the most part hard working America loving patriots that gave a whole lot for this country while in the military and continue to support the US Navy Warfighter so our freedoms are protected.
Now, we could have a discussion about federal worker benefits and compensation but that’s another subject. Lol
