The politically powerful Culinary Union, which represents 57,000 guest room attendants, servers, bellmen and others at resorts in Las Vegas in Reno, again played a key role in the Democratic turnout operation this year, with 350 workers taking a leave of absence to urge voters to turn out to the polls. In total, the union knocked 370,000 doors, had 80,000 one-on-one conversations with voters, made 45,000 personal calls, sent 1.8 million pieces of mail, sent regular emails and texts to members and ran video ads with 3.5 million views.
