In the July filing for the DA race, Democrat McMahon raised $151,640 for his campaign, while the Republican Illuzzi raised $73,000, according to the Board of Elections.
“The support that our campaign has received this month from Staten Islanders from all walks of life, across the political spectrum, from St. George to Tottenville and Rossville to Rosebank has been overwhelming," McMahon said.
"Our message of bringing justice, integrity and fairness to a modern and improved District Attorney’s office is clearly resonating with Staten Islanders."
After expenses, McMahon has $95,470 in his war chest while Illuzzi has $65,449, according to the Board of Elections.
Illuzzi, a former Assistant District Attorney in Manhattan, will square off against McMahon, a former congressman for Staten Island, in the race to replace Dan Donovan, who vacated his DA seat in May after he was elected to Congress.
So far, Illuzzi has got endorsements from Donovan, former Mayor Rudy Giulani, Councilman Steven Matteo and Assembly members Joe Borelli and Nicole Maliotakis.
McMahon has been endorsed by State Sen. Diane Savino, the New York State Court Officers Association and Assemblymen Matthew Titone and Michael Cusick.
The race for DA will likely happen during the regularly scheduled election in the fall, unless Gov. Andrew Cuomo sets a special election to replace Donovan, according to the New York Times.
