In the housing projects of Pittsburgh’s Northview Heights neighbourhood, vocal enthusiasm for this presidential election can be hard to come by.
I am out with two women, Leslie Hughes and Luwaunna Adams, whom I met two years ago when we were making a video in western Pennsylvania – a perennial battleground region in the US’s closest-fought swing state. The pair are members of the service workers’ union, which represents lower-income cleaners and security personnel. They are also two of the most effective and persuasive canvassers I have encountered.
