When you exercise your right to vote tomorrow, you have the right to do so free from any kind of intimidation. With that in mind, let's review what's permissible and what is not.
1) Can I Wear Buttons, Pins and Materials that endorse my favorite candidate?- Yes, so long as you do not actively campaign, and leave the polling place as soon as you vote. Poll workers, watchers and candidates with a watcher's certificate are prohibited from wearing anything endorsing any candidates, and may not campaign while inside the polling place.
2) When must people stop seeking my vote? All campaigning (electioneering) must be done at least 10 feet away from the polling place.
3) You've got three minutes. - You can only take three minutes in the polling booth, although election officials can grant you a longer time if nobody is waiting.
4) Can I help Auntie May cast her vote? - No. Unless her voter registration card contains a declaration that she has some kind of disability that makes it impossible for her to see the ballot, she's on her own. (Updated 12:42. - (The Lehigh County Registrar tells me there are forms voters can also fill out, requesting assistance from the Judge of Elections.)
5) Can campaigners hound me outside the door? Yes and No. It's America. People can lobby for their favorite candidate, but may not block your path to the voting plac, or practice any form of intimidation.
6) No cops! They have to stay 100' away, unless they're voting themselves or are called there to restore order or pick me up for an unpaid parking ticket.
7) What do I do if I see a problem? Call the elections office. In Northampton County, it's (610) 559-3055. In Lehigh County, it's (610) 782-3194. The law requires their Solicitor to be on duty and in the odffice from 7 AM until 10 PM. The Court will also assign a judge to make himself or herself available for any problems that arise.
