CLEVELAND (AP) - Crowds and pageantry are out. COVID-19 tests and masks are in.Presidential debates are typically some of the most exciting nights of the campaign season, drawing a crowd of thousands of staffers, media and guests.But this year, as with almost everything else, things are very, very different, with a long list of precautions in place.Instead of the usual auditorium setting, the debate is being hosted by the Cleveland Clinic and Case Western Reserve University in the 27,000-square-foot (2,500-square-meter) atrium of the Sheila and Eric Samson Pavilion on the clinic’s Health Education Campus.
