Biden gears up for Trump rematch with age and approval front and center

The worst-kept secret in Washington is out - but at 80, and with low approval ratings, the president faces challenges in his re-election bid

Legend has it that when the artist Benjamin West told King George III that George Washington, the first US president, had decided to resign, the king replied: If he does that, he will be the greatest man in the world."

Some urged Joe Biden, the 46th president, to follow suit and, at the age of 80, hand power to a new generation. Who were they kidding? The worst-kept secret in Washington is out: Biden is running for re-election next year.
