In the last Democratic debate, Joe Biden declared that he would nominate a woman as his vice-presidential running mate. That felt right at the time. But times have changed. Biden needs to go much, much further: At the Democratic convention he needs to name not just his vice president, but his entire cabinet. And it needs to be a totally different kind of cabinet — a national unity cabinet — from Democrats on the Bernie Sanders left to Republicans on the Mitt Romney right. Why?

Because while most people are playing nice right now managing this virus, the wreckage, pain and anger it will leave behind will require megadoses of solidarity and healing from the top.

And even if we get to the other side of this crisis by January, there are going to be a set of wrenching debates around who got bailed out and who didn’t and around how much civil liberty we should sacrifice to track and quarantine Covid-19 carriers until there is a vaccine. If handled on a partisan basis, those issues will rip our country apart.

In short, if this isn’t the time to leave behind the hyperpartisanship that has made it nearly impossible for us to do anything big and hard for two decades, then when?
