NOTE: Do you vote a paper ballot? Be sure to follow all instructions; especially be sure to sign the return ballot envelope.

In the August 2016 Primary Election. 2,349 paper ballots (advance and provisional) were challenged. The Board of Canvassers  accepted the Election Office’s recommendation to count or not to count those ballots. Of the 898 recommended NOT to count, 219 were not registered to vote. There were 272 who had “incorrect party affiliation change” which is only an issue in primary elections. Some ballots were not accepted due to problems with the return envelope, such as the envelope was not signed or signature did not match the one on file, incomplete information, photo ID was not shown to election worker, or voter had already voted. See a sample return envelope for guidance.
