I've seen conflicting reports about this but I'm not going to argue the point. I can certainly see why 20ft would be a problem.

It seems to me the counting authority should have set up some 4K CCTV gear, and/or 4K webcams on an internal network, for the duration. The pandemic gave them ample warning that physical distancing measures would be required.

The earlier post's premise--as pushed by Trump over Twitter--that Republican poll watchers were specifically targeted for exclusion, however, is factually wrong.
