I voted on the 7th. It was at a large indoor sports/concert venue. They had three lines that merged into one. It took about an hour total.
Everybody seemed cordial and was minding their own business. Nice mix of people.
Police seemed to occasionally appear out of nowhere.
I tried to vote on the 6th but I got to the door at 4:03 and I guess they close promptly @ 4.
I didn't didn't see any passive electioneering on the 7th but did see some people waving Trump flags behind the fence on the sidewalk in the back of the coliseum the day before. Not sure anybody could see them though.
They don't play around here with that during early voting, even if it's legal.
Usually early voting happens in a county or city building caddy corner to jails, a courthouse, sheriffs office, city police offices, federal offices a fire station. If any kind of incident ever happened it could be swarmed by LEO in a matter of seconds.
Election day is a different matter. There's dozens of polling station manned by three people. Signs pop up right at the 50 mark and frequently so do people screaming people.
