Nassau County Executive Edward Mangano raised nearly $1 million in the six months after winning re-election, while the county's GOP committee brought in $1.8 million in the period -- more than triple the amount of its Democratic counterpart, State Board of Elections filings show.

In Suffolk, County Executive Steve Bellone, a Democrat, raised $610,701 since January and has $1.26 million available, filings show.

Mangano, a Republican who won a second term in November, raised $993,939 from Jan. 1 to June 30, records show. More than half of the money came from individual contributors and another $228,055 from corporate firms.

Roughly $375,000 of the fundraising came last month during Mangano's annual golf outing at Bethpage State Park, said spokesman Brian Nevin. Another $250,000 was raised from his "County Executive Club," in which donors who give at least $5,000 meet Mangano four times a year at restaurants.

Mangano's fundraising included $32,000 from Rivkin Radler, the Uniondale law firm where Mangano served as "of counsel" before his election, and $20,000 from the Committee for Fair Property Taxes, a political action committee representing residential tax refund companies.

Mangano's campaign committee spent $445,228 during the filing period, including on meals, travel and fundraisers.

Mangano, who is not up for re-election again until 2017, now has $703,488 available. "Ed Mangano is focused on serving as county executive," Nevin said in a statement.

The Nassau Republican Committee's total was boosted by large fundraisers in January, March and May. The committee spent $1.17 million and has $1.4 million on hand. The Nassau Democratic Committee raised $592,484 between its three accounts, records show. The committees spent a combined $526,790 and now have a total of $65,693 available.

In Suffolk, Bellone is on pace to have $2 million in his campaign account by January, said Rich Schaffer, chairman of the Suffolk Democratic Party. Bellone is up for re-election in 2015.

Bellone's fundraising included a $45,000 contribution from a Brentwood limited liability company controlled by developer Jerry Walkoff and two $25,000 contributions from companies affiliated with New Hyde Park developer Glenwood Management Corp.

The county Democratic Committee raised $519,000 during the filing period, spent $339,878 and has $196,291 on hand.

The Suffolk County Republican Committee Housekeeping Account raised $102,300, spent $103,950 and had a closing balance of $1,338.56. The party has four other accounts. Filings for two were not available Wednesday, another reported no action and the Republican Chairman's Club raised $500, spent $1,500 and had a $227 balance.
