Much of this catalog of woes is impossible to quantify. But everyone sees the strain and emotional toll in their friends and families of a once-in-a-100-year public health crisis. Even if average new daily cases are currently on their way down, the pandemic will bequeath trauma that will take years to heal.

The psychological impact of the way America is feeling will be for history to describe. But it is having political consequences in real time.

A grungy mood in a nation divided in multiple ways is translating to ever-diminishing confidence in political leaders and the system itself. It also helps to explain why a summer economic spurt, a dip in inflation and more legislative success on Capitol Hill are unlikely to rescue Biden’s presidency.
