What should be done about the rest of the primaries?
By 
Biden now has what is for all practical purposes an insurmountable lead, even with the postponing of the Ohio primary. (To put it in sports terms, he’s a major league team with an 18 game lead with 27 games to go in the season. That team hasn’t clinched in mathematical terms, but you could run that season 1000 times in a simulation and it would win 1000 times).
Given this, it would seem wise to simply put off the remaining primaries for at least a couple of months (Many of these primaries feature other contests that need to be decided. ETA: There also needs to be a big push to convert both these contests and the November election to vote by mail). Sanders doesn’t seem like he’s going to concede, so at this point it appears as if the best course of action is to try to soothe his obviously immense ego, without giving him opportunities to continue to contest a nomination battle that in practical terms is already decided.
How to that I’ll leave up to psychology experts. But there certainly shouldn’t be any more “debates,” unless Sanders agrees to use them to double team Trump rather than attack the Democratic nominee.
