Joe Biden plans to accept the presidential nomination in person, but it remains to be seen whether there will be a significant in-person audience there to see it. The Democratic National Committee said in a statement that official business, including the votes to nominate Biden and his yet-to-be-named running mate, will take place virtually, with delegates being asked not to travel to Milwaukee.

It's the latest sign of how much the COVID-19 pandemic has upended American life and the 2020 presidential election, leading Biden and the party to abandon the usual trappings of an event that draws tens of thousands of people to the host city to mark the start of the general election campaign. Not even during the Civil War or World War II did the two major parties abandon in-person conventions with crowded arenas.
