Pennsylvania. It’s an open-carry state. There is no law that says anything about brandishing.
That said, if you point a gun at someone, you are responsible for whatever happens next, including bullets flying in your direction.
(I’m not a lawyer so there might actually be a law about brandishing. I’ve just never pointed a gun at anyone so just don’t come here waving your gat around all willy nilly.)
You need to find a better voting location. Mine has churros and Mt Dew.
