In addition to the roughly 800 ballots that were discounted due to allegations of fraud from the US Postal Service, another 2,300 ballots were not counted, according to the Paterson Press. In total, 19% of all the ballots cast were disqualified.
Of Paterson’s six ward seats that were voted on, four of them had a higher number of votes disqualified than the winner’s margin of victory. This means that in each of those, the discounted votes could have changed the outcome of the election.
