On course for 300-ish electoral college votes, the US president-elect aimed to “bind the wounds of division” and serve “all Americans”. The prospect of “one united people” was not so exotic to a man reared in the bipartisan midpoint of the 20th century.

Perhaps Donald Trump suppressed a smirk as he offered that olive branch four Novembers ago. But then Barack Obama, George W Bush and Bill Clinton made the same noises upon their own ascensions to the White House. Whether we blame them or the implacability of their opponents, each failed. No doubt, Joe Biden, who “doesn’t see red states and blue states”, will be fifth time lucky.

This is a crass moment, I know, to play down the change of president. Washington and other liberal cities caroused as news of Mr Biden’s projected victory spread on Saturday. Killjoys must — the ghastly demotic is fitting for once — read the room.
