It was the week when Joe Biden displayed rare bravery by stepping back from the Democratic nomination; a truly selfless act that will assure that his legacy will remain intact, no matter what happens in November…

Except it wasn’t. He didn’t. And it doesn’t.

We can ignore much of what passed in the past week in US politics as pure froth; the bleachy detergent released to the press and meant to make us think a politician’s fingers are as clean as their soul. Accepting any of it at face value is like buying into the marketing of some new phone that promises you a 24-hour battery when you know it will probably die on you somewhere during Newsnight.

The past week has been a succession of slick, atom-deep, spray-on finishes to the previously tarnished wreck of the Democratic nomination.
