Several hundred union members got on their feet and chanted "226" and "We vote! We win!"
Union workers stacked and bundled campaign door-hangers written in English and Spanish that featured the candidates and details about voting.
Donna Kelly-Yu, who works as a butler dispatcher at Caesars Palace, has been on a leave of absence from her job since late August to knock on doors and get people to the polls for a slate of union-endorsed Democrats. Kelly-Yu said she's been working sometimes 12 hours a day, seven days a week to talk to as many people as possible.
On Monday, she and a partner were planning to visit more than 220 houses.
