In the final fundraising push before the Nov. 3 vote in Staten Island’s hotly contested district attorney race, Democrat Michael McMahon garnered more than eight times the contributions Republican Joan Illuzzi did in September, according to campaign finance records filed Monday.

McMahon, a former Staten Island congressman and City Council representative, goes into the campaign’s final month with a war chest of $170,000, compared to Illuzzi’s $70,000, according to reports filed with the Board of Elections Friday.
