How a Harris win in US election could depend on Democrats in London

About 200,000 Americans live in the UK, and Democrats Abroad members are campaigning hard to get them to vote

On a chilly afternoon in central London, the battle for the US presidential election is being waged with no less fervour than if the campaigners were on the other side of the Atlantic.
