So estimate is 6,000 - 7,000 which looks about right based on vids and pics.
Massive overpromise blunder.
I looked for accounts of previous rallies in Tulsa and only found one from early 2016, at a smaller indoor venue where press accounts were ~9,000.
You can’t go to a Trump rally and wear a mask or social distance without being mocked (yeah I know a few did).
My takeaway is that the locals were more Covid-conscious than the campaign estimated.
This may translate into smaller rallies, but I wouldn’t automatically translate it into lost votes.
Most people know Trump is all bullshit all the time, that’s why they like him. Some portion of them are just not willing to risk their health.
