With coronavirus raising havoc across the country, James Freeman in the WSJ, reminds readers of the postponements of various state primaries. He also reports on Barbara Sprunt from NPR:

(Joe)Biden currently holds a more than 300 delegate lead in the race for the Democratic nomination.

During an online press conference Wednesday, Biden was asked about whether there should be more Democratic primary debates and answered, “I think we’ve had enough debates. I think we should get on with this.”

(Bernie) Sanders conceded that he substantially lagged Biden in the race, saying, “it’s going to be a very steep road,” but said there was value to holding more debates.

Considering the risks of the flu or coronavirus, concludes Mr. Freeman, what harm, but especially what benefit, in keeping both candidates isolated for the time being?
