Each of the incumbents faced challengers who ran campaigns promising change from the status quo.
For the three open town board seats, Chris J. Coschignano of Muttontown was seeking a third term, Elizabeth A. Faughnan of Locust Valley was running for a second term, and Joseph G. Pinto of Massapequa Park, who was appointed to fill a vacancy, was running for a first full term.
They all seemed to edge out challengers Matthew T. Meng, Douglas G. Watson and Erin A. Reilley, all Democrats.
A century of GOP rule continued, with Supervisor Kate Murray poised to win election to her fourth term and the Republican board expected to hold on to its 6-to-1 majority.
"I'd like to think it was a referendum on the whole package, all we do in the Town of Hempstead, not just one project," Murray said of the proposed Lighthouse Project.
Murray had forged ahead by the time results from almost all of the election districts were counted.
All three incumbents on the town board faced first-time opponents. Republican Councilman Anthony Santino of East Rockaway was leading Jean Brett-Leach of Rockville Centre. Republican Councilman Gary Hudes appeared to best opponent Matt Hynes.
And the board's lone Democrat, Dorothy Goosby, was leading by a large margin in a contest with Democrat-turned-Republican challenger Tracy Worthy.
In the town clerk race, incumbent Republican Mark A. Bonilla, seeking his fourth term, soundly triumphed over Democrat Anthony Rattoballi.
Supervisor Jon Kaiman, seeking a fourth term, appeared to barely beat out Lee Tu, a manager at a public accounting firm. Kaiman, 47, a Democrat who said his leadership has built residents' trust, focused on his record of improving services and maintaining the town's fiscal health in tough times.
Tu, 34, a Republican, made his priorities lowering taxes, improving transparency and creating a property owners' bill of rights.
Three North Hempstead town board seats were contested, as was the town clerk's office. Republican Karin B. Campbell lost to Democrat Viviana Russell in the District 1 position; Republican incumbent Angelo P. Ferrara beat out Democrat Mathew G. Palakunnathu in District 3; and Republican Louis F. Chisari lost to Democratic incumbent Lee Seeman in District 5.
Democratic incumbent Leslie C. Gross held the lead over Republican Jon P. Wicks.
