Probably illegal to bring anything into a voting booth, but put it on your car and park in front of the election site.
When someone asks you what it means, tell them that your are voting “to get the crap out of Congress.”
That’s funny. As far as I’m concerned, they can make me take it outside. I’ve brought umbrellas into the polling area and they are a lot more dangerous than a plunger. But your point is well taken and you are most likely right.
I think the reason I could probably get away with it is I live in a very sedate area so some of the nasty things than happen in other places just don’t happen here.
