Kamala Harris is turning out not to be a healing influence for the Democratic Party as she tours the country promoting her memoir, 107 Days (Simon & Schuster, £25). She plainly regards this as payback time — on Joe Biden chiefly — and the effect on a demoralised party has not been good, however cathartic for her.

So what’s in the memoir that is proving so divisive?

There’s her plain sense of grievance, for one thing, as she dwells on the slimness of Trump’s victory: “His victory was whisker-thin. He beat me by 1.5 percentage points in one of the closest elections in a century. A third of the electorate voted for me. But a third of the electorate stayed home. That means that two-thirds of our country did not elect Donald Trump.”
