Union leaders are often aspiring politicians. Richard Trumka would be an example of this.
So, they instruct the union members how to vote, which is always whichever way will benefit the leaders the most.
Union members are often to dumb to think for themselves.... ""As long as the union keeps me working, I'll do as I'm told"" (so much for independent thought).
This thought process or lack there of usually bites them in the ass. As an example the UMWA backed both Obama and Clinton.... 2 candidates that openly hated the coal industry and Obama won twice...Go figure.
