The big headline tonight is obviously that Biden is sewing up the Democratic nomination. But from my vantage point in Illinois, it's hard not to focus on the impact that the coronavirus crisis has had on this latest round of primaries. There has been some criticism of Illinois Gov. J.B. Pritzker for not postponing the election or moving to exclusively vote-by-mail, but whatever you think of that choice, it's clear that voters today were profoundly affected by it -- whether they had to wait in line because their precincts were suddenly closed or didn't show up at all. We might be heading into a lull right now in the primary, but it's not easy to know how we should handle elections during a pandemic, and today didn't give us any great answers.
