Patch published a detailed synopsis of how New Jersey’s first vote-by-mail elections are going to work. 2020 is the first year that mail-in ballot voting will be taking place statewide.
Vote by Mail ballots can be returned by the USPS, placed in ballot boxes Gov. Murphy is situating around the state, turned in at polling locations and at county offices.
You can also cast your vote by visiting a polling location, but the ballot will be provisional since the staff will not be able to tell whether you have already sent in your mail-in ballot.
