What is happening at the debate site, Case Western Reserve University?

All those potentially positive people without masks. How many may have been nearby coming and going? And support people in the debate hall. The location needs to ge cleaned.
Honestly, though, there is some karma in that they allowed attendees to not wear masks. They should have been warned -- "no masks, no attendance" ahead of time and/ or had a portable pexiglass separation with loud air cleaning system ready to put in place around the maskless. If the staff who asked them to put on masks get sick, I hope they sue. And if not, perhaps sue the Trump campaign, debate commission, and even CWU for reckless endangerment and emotional distress.
