It’s an old trick. Before pro wrestling got big matches were typically held in places like the old Sunnyside Arena in Queens, the Hesterly Armory in Tampa, the Olympic Auditorium in LA, etc, places that had at most a 1000 seat capacity and most times weren’t even half full. They would position the cameras and adjust the audio in such a way as to make those places seem larger and more crowded and noisier than they actually were. They need resort to these tricks whenever a Dem candidate spews their BS to the relatively few who bother to listen.
I went to Sunnyside Arena in Queens with my Dad in 1948 and saw Gorgeous George and Primo Carnera. I had won front row seats on the Dennis James radio sports show. I was 12 years old. Thanks for bringing back that memory.
