Many twitter photos featuring stuff like this.
Where I live it is 25 feet. We have a nice demarkation line they don’t go past.
Only 2 campaigners, one being from the fire department for a local issue, today.
I have shown up to vote and seen upwards of 15 people electioneering, including a US Senatorial candidate and a US Rep candidate.
For demographic purposes, it’s about 80 D/20 R, upper middle class. Lots of small business owners, lawyers, doctors, college professors. They vote liberal until it comes to messing with their school district.
