Retired NYPD detective and private security honcho Mike Sapraicone has $500,000 in his campaign treasury in a bid to topple indicted Rep. George Santos in the 2024 GOP primary for New York’s wealthiest congressional district.

Sapraicone, 67, generated $580,000 in revenue — about half in donations from more than 200 individuals and the rest from his own fortune — since announcing his candidacy for the 3rd Congressional District in July, his campaign reports.

He has more than $500,000 in cash on hand to spend.

“I have had the opportunity to speak with hundreds of my neighbors in the district, from life-long Republicans to those who have voted across the aisle in the past, and they all share rightful concerns about the irresponsible, dangerous policies of Democrats,” Sapraicone told The Post.

“My message on issues like public safety, border security, and fiscal responsibility resonate with New Yorkers as thousands signed up for my email newsletter and more than 200 people who generously supported my campaign.” 

In answer to the hefty war chest, Santos replied: “Good for him,” and noted of numerous candidates seeking to unseat him, “The more, the merrier.”

The beleaguered lawmaker has admitted to repeatedly lying about his background and was charged with a 13-count federal indictment including multiple-federal felony fraud, money laundering, theft of public funds, and false statement counts in May.

Through July, Santos’s campaign reported having $86,438.88, and owing $630,000 in loans, according to filings with the Federal Elections Commission.

“I am not raising money now. I’m too busy working for the American people. That’s next year,” Santos told The Post.

Given his legal woes, some political insiders question if Santos will seek re-election and if so, whether he can survive a competitive primary. While admitting to numerous lies about his personal life, he has denied the accusations in the criminal case against him.

The Nassau County Republican Party establishment has abandoned him, and Democrats are chomping at the bit to reclaim the seat, previously held by former Democratic Rep. Tom Suozzi.

The 3rd Congressional District takes in much of Nassau County and parts of Queens near the Long Island border.

Democrats vying for the seat include former state Sen. Ana Kaplan, Nassau County legislator Josh Lafazan, St. John’s University professor William Murphy, activist Zak Malamed and former prosecutor Austin Chen, CEO of Gramercy Surgery Center and a major in the Army Reserves.

Aside from Sapraicone, at least one other Republican candidate has emerged — Kellen Curry, an Afghanistan war veteran and former vice president at JPMorgan.
