Monday marks the start of the long-awaited Democratic National Convention. The four-day event when it was announced a year ago was originally going to take place in Milwaukee, dropping $200 million into the regional economy and attracting 50,000 visitors. But now, it’s mostly virtual because of the coronavirus pandemic. Joe Biden will accept his party’s nomination from his home state, Delaware. Most other speeches will occur in other places, too, although a few will be broadcast from Milwaukee.
