The old sports betting saying “skin in the game” doesn’t apply here.
By all accounts, betting on the U.S. presidential election is a popular activity in the regulated UK betting market, as well as through unregulated channels — largely offshore online sportsbooks — that are accessible to Americans. It makes sense, given that it happens once every four years, and the year of the election features increasingly wall-to-wall news coverage of the spectacle, which has been sportified thoroughly, especially since the invention and ubiquitous use of the television.
