Ahead of today’s primary elections, voters in a suburban Westchester County town opened their mailboxes to find a harsh attack on its top local elected official.

Harrison Supervisor and Mayor Richard Dionisio, who is facing challenges in the Republican, Democratic and Conservative Party primaries — he’s running for all three lines — is “The Most Corrupt Man in NY,” the mailer told voters, alongside a large photo of a recent New York Focus article. (Last month, New York Focus reported on Dionisio’s financial windfall following a controversial rezoning he helped push through.)

Yet the source of the funding behind the mailer is itself murky.

The mailer’s fine print says it was paid for a “David, S. Miram.” It provides a contact email address (stoprich10528@gmail.com) and states that it was not funded by a candidate.

New York Focus could not locate a person named “S. Miram David.” But there is a Harrison resident named Shoshana David, who unsuccessfully ran for Congress as a Republican in 2022. A database of New York City marriage records lists her middle name as “Miriam,” similar to the mailer’s “Miram.”

David has been married to a fellow Republican, Joshua Eisen, who has himself run unsuccessfully for Congress and US Senate.

The Gmail address listed on the mailer did not respond to New York Focus. David and Eisen could not be reached for comment on Monday.

According to the State Board of Elections website, information about mailer’s funding has not been disclosed to the campaign finance regulators.

Communications attacking a candidate within a month of an election and sent to more than 500 individuals require the creator to create an independent expenditure committee and disclose donors and spending. It’s not clear how many people received the mailer in the 30,000-person town and village.

David is a registered Republican. So is Dionisio, who was once the favored candidate of the local Republican Party. But Dionisio is now on the outs with the party establishment, which backed a different candidate in the Republican primary on Tuesday.

In the wake of that split, traditional party allegiances have shifted.

The Democratic Party — which often faces uphill odds in the Republican-heavy town — decided to back Dionisio and allow him to run on its ballot line. Still, Dionisio is also facing a Democratic challenger for that ballot line. The mailer obtained by New York Focus was sent to the home of a registered Democratic voter.

The local Conservative Party leadership also backed Dionisio, but he faces a third primary for that ballot line from yet another challenger.

David and Eisen jointly own three homes in Harrison, according to town records. None are geographically close to the controversial proposed housing project which was enabled by a rezoning that Dionisio took steps to push through — and which is at the center of the mailer’s accusations.

As an unsuccessful candidate in 2020, Eisen faced scrutiny over an alleged history harassing legal opponents and their families over email, as well as documented instances of using racial slurs.

At New York Focus, our central mission is to help readers better understand how New York really works. If you think this article succeeded, please consider supporting our mission and making more stories like this one possible.

New York is an incongruous state. We’re home to fabulous wealth — if the state were a country, it would have the tenth largest economy in the world — but also the highest rate of wealth inequality. We’re among the most diverse – but also the most segregated. We passed the nation’s most ambitious climate law — but haven’t been meeting its deadlines and continue to subsidize industries hastening the climate crisis.

As New York’s only statewide nonprofit news publication, our journalism exists to help you make sense of these contradictions. Our work scrutinizes how power works in the state, unpacks who’s really calling the shots, and reveals how obscure decisions shape ordinary New Yorkers’ lives.

In the last two decades, the number of local news outlets in New York has been nearly slashed in half, allowing elected officials and powerful individuals to increasingly operate in the dark — with the average New Yorker none the wiser.

We’re on a mission to change that. Our work has already shown what can happen when those with power know that someone is watching, with stories that have prompted policy changes and spurred legislation. We have ambitious plans for the rest of the year and beyond, including tackling new beats and more hard-hitting stories — but we need your help to make them a reality.

If you’re able, please consider supporting our journalism with a one-time gift or a monthly gift. We can't do this work without you.

Thank you,
