Nassau Democrats nominated Legis. Laura Curran Wednesday night as their pick for county executive, choosing the second-term lawmaker over the insurgent campaign of county Comptroller George Maragos.

The party committee chose Curran (D-Baldwin), who would be Nassau’s first female county executive nominee, during its convention at the Cradle of Aviation Museum in Garden City.

Curran told a crowd of roughly 400 Democrats that she had a solution to wipe out county patronage, repair its much maligned contracting system, and fix the way property taxes are assessed.

“Residents are sick and tired of watching their hard-earned tax dollars fund a job program for the elected and the connected and a PR campaign for their perennial re-election bid,” Curran said.

Maragos, who changed his party affiliation from Republican to Democrat last year, did not attend the convention.

“Democratic Party voters will be selecting their nominee on September 12th, and the party bosses are endorsing someone unqualified, inexperienced and beholden to special interests,” according to a statement from Maragos, who is running an “Independent Democrat” ticket challenging party-backed candidates.

Nassau Democratic Party chairman Jay Jacobs called Curran the “only candidate left who will bring integrity to the office and clean up the mess brought on by years of Republican incompetence and corruption.”

Curran announced her candidacy in November and has coalesced support from county and state lawmakers and labor officials. Last week, Assemb. Charles Lavine (D-Glen Cove) ended his candidacy for county executive and backed Curran.

Lavine nominated Curran Wednesday night, calling her “tough, smart and independent.”

Also Wednesday Rep. Thomas Suozzi (D-Glen Cove) — who served two terms as county executive and was nominated four times for the seat — joined Legis. Arnold Drucker (D-Plainview), and Delia DeRiggi-Whitton (D-Glen Cove), in endorsing Curran and the countywide Democratic slate.

Nassau Democrats made several other nominations for legislative seats Wednesday night as they attempt to win control of the county legislature, where the GOP holds a 12-7 advantage.

Among those nominated: Freeport trustee Debra Mule for the 5th District seat being vacated by Curran; Eileen Napolitano for the 13th District seat being vacated by retiring presiding officer Norma Gonsalves (R-East Meadow), and Joshua Lafazan, who in 2012 won a spot on the Syosset Board of Education at age 18, against incumbent Legis. Donald MacKenzie (R-Oyster Bay) in the 18th District.

Joining Curran on the countywide ticket are comptroller candidate and Long Beach City Manager Jack Schnirman and clerk candidate Dean Bennett, who runs a consulting firm.

Nassau Republicans have nominated former state Sen. Jack Martins as their county executive candidate.
