Long Islanders are voting with their check books in the race for New York City mayor.

A News 12 statistical analysis of the latest data available from the New York City Campaign Finance Board finds that in August, Long Islanders spent tens of thousands of dollars supporting the four leading candidates for mayor.

From Aug. 1 to Aug. 18, former Gov. Andrew Cuomo (D) led the field with $47,176 earned from individual donors. Cuomo also had the highest mean donation, averaging $1,179 per individual contribution.

The front runner in the race, Democratic nominee and state Assemblyman Zohran Mamdani, earned $26,495 from individual donors on Long Island, with an average donation of $731.

Curtis Sliwa, the lone Republican in the race, had more donors over the same time period than Cuomo, Mamdani and incumbent Mayor Eric Adams combined. Sliwa had 152 individual donors on Long Island over the first 18 days in August. But Sliwa averaged just $69 per individual contribution, totaling $10,426.

Adams trailed in the field among cash raised and the number of donors on Long Island in August. Nine donors contributed $6,575.

Political Michael Dawidziak, who primarily works with Republicans, says Long Island's interest in New York city's race is not surprising.

"Long Island should be concerned about this and people clearly are and they're saying it with their checkbook," Dawidziak said.

"Democrats on Long Island are going to be more moderate and they're going to want to probably line up with a Cuomo and Adams, whereas Republicans might be ramped up more to donate to Sliwa."

"So part of it is is ideological. But then of course, you know, we're not naive here. A lot of people donate because of self-interest. You might have business interest in the city, particularly out east where you have a lot of people who have second homes out east, they might be registered out east, but they have business interests and they want to have obviously some influence on the people who are going to be making the decisions in the city."

News 12's campaign donor analysis focused solely on individual donors on Long Island with data from the latest month available.
