And also illegal within the polling place and outside to some distance.

No t-shirts, no hats, nothing.

within 50 or 100 feet of the polling place. No one stopped them? More signs of facism.

Hillary scarf in 2016, though. Among various symbols are donkeys in heels and lipstick, but I don't think anyone noticed. You have to look.

not sure if it's national or only within one state. I worked as a poll inspector in California a few years ago and electioneering was not permitted within a polling place (hats, shirts, buttons, signs).

within so many feet of the polling place. But maybe since the Orange Dictator is not on the ballot they can get away with it?
Just shows me they are stupid.

The rule prohibits electioneering within the flags - and directs the placing of flags at 100 feet from the entrance to the polling place.

Often the flags are placed at the street (well over 100 feet from entrance to the polling place) - and if you are canvassing beyond 100 feet - but inside the improperly placed flags - you're in limbo. It's hard to get pollworkers of the opposite party to concede that they placed the flags incorrectly - so it frequently requires someone from the board of elections to come out to correct things (in the mean time you've generally lost a significant portion of the polling period, unless you want to risk arrest).

Not that I've ever been threatened with arrest for canvassing inside the flags, or anything.

The funniest time was when the Repubicans were canvassing on one side of the driveway and we were canvassing on the other. The Republicans measured off the 100 feet to make sure they were legal. The Republican judge came out and swore a blue streak at us and ordered us outside the flage (about 200 feet from the entrance). Never said a word to the Republican canvassers - who had picked the location. . . . and rather than be arrested, we temporarily moved behind the flags and called the board of elections. To their credit, the Republican canvassers moved, too. It took more than an hour to resolve it (the angry Republican judge was ordered to place the flags at 100 feet).

Not quite what you asked - since you want to exclude someone. But the same general law applies.

It should not be.

A judge should have asked them to remove the hats, or leave.

Just pollworkers, not police, around and many of them elderly, or don't know the details of the law. Usually, the offender is nice about it and takes the hat or button off if asked, but not always.

Occasionally you hear about someone being told to take off a t-shirt and the huge fuss they make about it. So the police have to be called, and the lines held up until it's over. And whose vote has ever been changed because some asshole brought in a button or t-shirt?

Yeah, I know the law is the law, but sometimes just not worth the hassles.

There is no standard.

There are flags and signs that mark that distance out and violators should be reported to the election officials.

at polling places.

In Ohio, between the flags at the entrance of the polling place and the doors to the polling place there is to be no campaign signs or clothing thaat supports a candidate nor electioneering.

I will be wearing a Democratic blue shirt and a US flag bow tie. I'll wear them again on voting day.
