This depends STATE BY STATE (or town by town), so check out your own state's rules. As for everywhere, only poll workers are banned from this, and people holding up signs for candidates have to be a certain distance from the building.

This word of caution is from someone who has worked the polls a lot in the past: More and more I’m seeing women announcing they will be voting with shirts, buttons, masks or hats that say “Ruth Send Me”, or something similar. [Transcriptor Annotation: the late Supremecourt Justice Ruth Bader Ginsburg. /End of Annotation.] Remember: political messages aren’t allowed in the polling place (that could include [Black Lives Matter] shirts, unfortunately.) Also unfortunately, messages can be interpreted by whoever is in charge. It could mean, in some cases, that a voter wearing a shirt they believe is political can be denied the right to vote after waiting in line for hours. Approach this election strategically and vote smarter and cleaner than ever have before. Understand that the other side will do what it takes to advance their agenda. We need to vote in record numbers. But we need to vote smart. We can wear that wonderful “Ruth send me” shirt or mask when we get home, and raise a glass in her memory. Please copy, or paraphrase, and share with the groups you are members of, as appropriate. Help spread the word so that every vote counts! We all know what’s at stake. Do not throw away your shot.

Thank you for the image description!
I remember a story of someone having trouble at the polls because they were wearing a Stark/Rogers (as in Tony Stark and Steve Rogers, the very fictional people) so BE CAREFUL.
