Although it is typical for Big Labor to throw all of its support behind the Democratic candidate for president, and for most of union member voters to follow suit, this year could be quite different. Democrat supporters are more squeamish about Clinton, and Trump is just too wild of a wild card to really know whose hearts are being captured by his rhetoric. It does seem clear that this year more than others, union membership are not towing the line behind leadership, which could be particularly crucial in labor-dominated hinge states like Nevada.
