Trump or Biden? US voters head to polls on election day

There has never been an election quite like this.

The queues for Covid tests rival the queues at polling stations – with some 90,000 new cases a day.

This is the backdrop against which the president – himself a Covid survivor – has been campaigning with astonishing, almost frantic energy. He came back to the White House last night at 3am, after a blitz of seven rallies in five states.

His rival Joe Biden has called for an end to a presidency that has “fanned the flames of hate”.

And another first: overnight the White House was surrounded by an unscalable fence in case of unrest, a fitting precaution for a president who ran on the promise of building walls, not tearing them down.
