A great, 2016-important example is the Culinary Workers in Nevada. The Culinary union (as it is known) is part of UNITE HERE, but has its own discretion to endorse as it sees fit. It is very politically powerful in Las Vegas, thanks to the hotels it has organized, and Vegas is critical to Nevada. That makes the Culinary's endorsement in that early state probably more important to a candidate than the national UNITE HERE endorsement.
