 There was a new CNN poll. It found Biden losing to Trump by six points, Harris losing by only two points. Other internal Democratic polling has been leaked, including by a group called Open Labs. Looks there, too, like Harris is now outperforming Biden against Donald Trump. In polls before now, she's performed similarly, sometimes a point or two worse. So far, the conventional wisdom has held that Biden may be weak, but Harris is also too weak. But why? Why?
