Here’s one case—a single incident, but much too large a case to be dismissed for that.

Paterson, NJ, with a population of 145,000, last month held—rather, is holding, since the city isn’t done counting votes—an election for City Council, among other positions. The election was done by mail-in voting since the Powers that Be considered the city’s Wuhan Virus situation that serious.

16,747 vote-by-mail ballots were received, but only 13,557 votes were counted. More than 3,190 votes, 19% of the total ballots cast, were disqualified by the board of elections.

Nineteen per cent of the votes have been tossed.

Why?

Over 800 ballots in Paterson were invalidated for appearing in mailboxes improperly bundled together—including a one mailbox where hundreds of ballots were in a single packet. The bundles were turned over to law enforcement to investigate potential criminal activity related to the collection of the ballots.
The board of elections disqualified another 2,300 ballots after concluding that the signatures on them did not match the signatures on voter records.

There’s more:

Reporting by NBC further uncovered citizens of Paterson who are listed as having voted, but who told the news outlet they never received a ballot and did not vote. One woman, Ramona Javier, after being shown the list of people on her block who allegedly voted, told the outlet she knew of eight family members and neighbors who were wrongly listed. “We did not receive vote-by-mail ballots and thus we did not vote,” she said. “This is corruption. This is fraud.”

And

There were multiple reports that large numbers of mail-in ballots were left on the lobby floors of apartment buildings and not delivered to residents’ individual mailboxes, further casting doubt on the integrity of the election.

But who cares, right? It’s only 3,200 votes that were…wrong.

In a single ward of one council seat race, 24% of the votes cast were tossed by the State’s Board of Elections.

One case? Not so much. Statewide, across all of its 31 elections, the Elections Board had to “disqualify” 9.6% of the mail-in ballots cast. Even with Paterson’s failures discounted, the Statewide failure rate is over 8%.

Mail-in ballots, which have none of the controls of absentee ballots, are a petri dish for the voter fraud that Progressive-Democrats insist is a right-wing conspiracy.
