At its heart is the Culinary Union, widely dubbed the state’s most powerful political force after the parties. It represents 60,000 hospitality workers - barman, cooks, casino cleaners, valets; the people who keep Vegas running.

The economic impact of the pandemic on them is mind-boggling. Union officials say 98 per cent of its members were forced out of work when the lockdowns first came in the spring, placed on furlough schemes.

Still 50 per cent have not returned to work. That has not stopped their campaigning though. The union has a team of 350 full-time canvassers, hospitality employees out of work who are paid $25 an hour to knock doors in favour of Mr Biden, the Democratic presidential nominee who the union has endorsed.

On a scorching weekday afternoon two union members, Larry, a hotel porter, and Paola, a casino housekeeper, work their way along the suburban streets of North East Las Vegas.
