Confessions of a voter fraudster on the US left: I was a master at fixing mail-in ballots. By Jon Levine.

A top Democratic operative says voter fraud, especially with mail-in ballots, is no myth. And he knows this because he’s been doing it, on a grand scale, for decades. ...

The political insider, who spoke on condition of anonymity because he fears prosecution, said fraud is more the rule than the exception. His dirty work has taken him through the weeds of municipal and federal elections in Paterson, Atlantic City, Camden, Newark, Hoboken and Hudson County and his fingerprints can be found in local legislative, mayoral and congressional races across the Garden State. Some of the biggest names and highest office holders in New Jersey have benefited from his tricks, according to campaign records The Post reviewed.

“An election that is swayed by 500 votes, 1,000 votes — it can make a difference,” the tipster said. “It could be enough to flip states.”

The whisteblower — whose identity, rap sheet and long history working as a consultant to various campaigns were confirmed by The Post — says he not only changed ballots himself over the years, but led teams of fraudsters and mentored at least 20 operatives in New Jersey, New York and Pennsylvania — a critical 2020 swing state.

“There is no race in New Jersey — from city council to United States Senate — that we haven’t worked on,” the tipster said. …

A Bernie Sanders die-hard with no horse in the presidential race, he said he felt compelled to come forward in the hope that states would act now to fix the glaring security problems present in mail-in ballots.

“This is a real thing,” he said. “And there is going to be a f–king war coming November 3rd over this stuff … If they knew how the sausage was made, they could fix it.”

Mail-in votes are easy to change:

Mail-in voting can be complicated — tough enough that 84,000 New Yorkers had their mailed votes thrown out in the June 23 Democratic presidential primary for incorrectly filling them out.

But for political pros, they’re a piece of cake. In New Jersey, for example, it begins with a blank mail-in ballot delivered to a registered voter in a large envelope. Inside the packet is a return envelope, a “certificate of mail in voter” which the voter must sign, and the ballot itself.

That’s when the election-rigger springs into action.

Phony ballots replace the real ballots:

The ballot has no specific security features — like a stamp or a watermark — so the insider said he would just make his own ballots.

“I just put [the ballot] through the copy machine and it comes out the same way,” the insider said.

But the return envelopes are “more secure than the ballot. You could never recreate the envelope,” he said. So they had to be collected from real voters.

He would have his operatives fan out, going house to house, convincing voters to let them mail completed ballots on their behalf as a public service. The fraudster and his minions would then take the sealed envelopes home and hold them over boiling water.

“You have to steam it to loosen the glue,” said the insider.

He then would remove the real ballot, place the counterfeit ballot inside the signed certificate, and reseal the envelope.

“Five minutes per ballot tops,” said the insider. …

Postmen dump votes they don’t like:

The tipster said sometimes postal employees are in on the scam.

“You have a postman who is a rabid anti-Trump guy and he’s working in Bedminster or some Republican stronghold … He can take those [filled-out] ballots, and knowing 95% are going to a Republican, he can just throw those in the garbage.” …

Voter impersonation is easy, when there is no voter ID:

When all else failed, the insider would send operatives to vote live in polling stations, particularly in states like New Jersey and New York that do not require voter ID. …

The best targets were registered voters who routinely skip presidential or municipal elections — information which is publicly available.

“You fill out these index cards with that person’s name and district and you go around the city and say, ‘You’re going to be him, you’re going to be him,’” the insider said of how he dispatched his teams of dirty-tricksters.

At the polling place, the fake voter would sign in, “get on line and … vote,” the insider said. The impostors would simply recreate the signature that already appears in the voter roll as best they could. In the rare instance that a real voter had already signed in and cast a ballot, the impersonator would just chalk it up to an innocent mistake and bolt.

Bribes:

The tipster said New Jersey homeless shelters offered a nearly inexhaustible pool of reliable — buyable — voters.

“They get to register where they live in and they go to the polls and vote,” he said, laughing at the roughly $174 per vote Mike Bloomberg spent to win his third mayoral term. He said he could have delivered the same result at a 70 percent discount — like when Frank “Pupie” Raia, a real estate developer and Hoboken nabob, was convicted last year on federal charges for paying low-income residents 50 bucks a pop to vote how he wanted during a 2013 municipal election.

And that’s how the Pros on the left do it.

We’re probably going to be hearing a lot about this in the aftermath of the November 3 election, sadly.
