The marine band struck up a familiar theme. The door of the Oval Office swung open. Out strode the president and first lady to address an expectant crowd – that is, the real first lady, Jill Biden, and the president that fans of the TV show The West Wing used to secretly crave: Jed Bartlet, alias actor Martin Sheen.
After a decade in which US politics has often felt like the work of a hyper-imaginative screenwriter, with ever more unlikely plot twists including the election of a reality TV star, it felt strangely natural to see Sheen stepping into the shoes of Joe Biden as his show’s theme music filled the Rose Garden.
