In New York’s 90th Assembly District, two candidates seek to succeed retiring Assemblyman Nader Sayegh: Democratic candidate Frank Jereis, Sayegh’s chief of staff, and Republican candidate John Isaac, a financial-services professional who unsuccessfully ran for the seat in 2024. The district lies entirely within Yonkers.
(For voting information, please see our voter information box below.)
Frank Jereis — Democrat
At 25, Frank Jereis comes from a politically connected Yonkers family. His mother is a longtime Democratic ward leader and his father served as chair of the Yonkers Republican Party, but more recently has been engaged in city Democratic politics.
Jereis was Sayegh’s chief of staff for more than two years. He is also executive director of the Yonkers Democratic Party and a Democratic district leader. Yonkers Democratic Party Chair Thomas Meier has referred to Jereis as “son of the Yonkers Democratic Party.” Jereis has also worked at the Yonkers Commission on Human Rights. He earned his undergraduate degree from Hunter College and a law degree from New York Law School. He was admitted to the New York State Bar this year.
Jereis emphasizes his familiarity with the legislative process and the relationships he has developed with state and local officials. He argues that his work in Sayegh’s office has prepared him to represent the district as soon as he arrives in Albany. Jereis has the support of the Yonkers Democratic Party and a range of elected officials and labor organizations. He defeated Jeannette Garcia in the June Democratic primary, winning approximately 57% of the vote to Garcia’s 43%.
Through Sept. 28, Jereis raised $147,318 from donors and received $253,613 in public matching funds.
John Isaac — Republican
John Isaac is a financial-services professional making his second bid for the 90th Assembly District seat. The Republican candidate challenged Assemblyman Nader Sayegh in 2024, losing 56.4% to 43.5%.
Isaac immigrated to the United States from Kerala, India, at age 19 and has spent more than three decades working in financial services. His professional experience includes positions with Merrill Lynch and MetLife, and he currently is a vice president and financial advisor at Forest Hills Financial Group.
Isaac has received $117,846 in public matching funds for his campaign.

What the Financial Disclosures Reveal: Different Fundraising Networks, Different Reliance on Public Financing
Because Jereis is a Democratic Party insider with strong connections to the district’s political establishment, it’s not a surprise that he outraised and outspent Isaac. The Jereis campaign received $400,931 in contributions and matching funds, compared to Isaac’s $140,264. Big donors stepped up to support Jereis — 35% of his donations came from individuals who gave $1,000 or more. Isaac reported no support from big donors.
The figures show how New York’s public matching-funds program can provide significant campaign resources to candidates with very different levels of private fundraising. Jereis collected $253,613 in public matching funds to Isaac’s $117,846. Your taxpayer dollars came to 63% of the money raised by Jereis, and 84% of what Isaac raised.
Jereis reported $147,318 in private contributions from 314 identified contributors, compared with $22,418 from 168 contributors for Isaac. Jereis thus raised more than six times as much private money. Jereis received $52,200 from 31 individuals who each gave $1,000 or more, while Isaac’s records showed no donors at that level. Jereis also received $12,980 from unions and $14,480 from business and professional donors.
Isaac got $22,418 in private contributions, and approximately $16,049—about 72%—came from individuals who gave $250 or less in total. His reviewed donor records showed no contributions classified as corporate, LLC, PAC or labor-union donations. All of his contributions came from individuals.
Jereis is far outspending Isaac. Through Sept. 28, Jereis reported approximately $398,454 in campaign expenditures, compared with $116,194 for Isaac.
