Clarke, 40, is running on the Progressive line. He lives in Jericho and has a law practice in Farmingdale with running mate Blaire Fellows. Clarke unsuccessfully ran in the 3rd Congressional District Democratic primary in 2016 and was the Democratic candidate in the 17th District State Assembly race in 2014. He has a bachelor’s degree in philosophy and classics from Hunter College and a law degree from Touro Law Center. Clarke grew up in Freeport. He is not married.

Clarke said that fighting corruption and making town government more efficient and professional are priorities. He’s a Democrat, but he said that by running on a third-party line, he isn’t beholden to Democratic leaders and would be free to hire employees for their expertise, not their party ties. “Until you divorce yourself from being controlled by the party heads, you’re not going to be able to do anything about nepotism, you’re not going to be able to do anything about cronyism, or pay-to-play politics,” he said. Clarke said he would comb the town budget to look for inefficiencies, duplicative services and patronage jobs, and seek more federal and state grants, along with other new revenue sources. “I don’t think there’s an income problem,” he said of the town’s financial woes. “We get enough money in taxes.” Clarke said he opposes Supervisor Joseph Saladino’s plan for an inspector general, calling it a “useless position” with duties that could be performed by current employees.

Herman, 63, of Woodbury, is running on the Democratic, Working Families and Women’s Equality party lines. He is dentist and served on the Syosset Central School District school board for 18 years, including six as president. He is the president of the Gates Ridge Civic Association. He received his bachelor’s degree in psychology from the University of Maryland in College Park and his dentistry degree at the University of Maryland in Baltimore. He also received a master’s degree in medical ethics from Creighton University in Nebraska. He is married and has three adult sons.

Herman said the three big issues facing Oyster Bay are corruption, high taxes and road repairs. “The corruption actually has influenced the taxes so our taxes went up 11.5 percent this year,” Herman said. The town’s budget process needs to be changed, criticizing the town’s proposed 2018 budget for not containing a capital plan, Herman said. He said the town should have a publicly accessible online system to track road repairs. The town needs to raise revenue in order to lower taxes without cutting services, he said. “The way we’re going to increase revenue is transit-oriented development,” Herman said. Herman said modeling development around train stations such as Farmingdale will attract more businesses and increase revenue. The town also needs an outside auditor to examine how the town spends money and how it got so deeply into debt, Herman said.

Mangelli, 51, of Bayville, is running on the Reform Party line. He was the Democratic candidate for supervisor in 2015, losing by 99 votes to then-incumbent John Venditto, who resigned in January after his arrest on corruption charges. Mangelli, an attorney, has a bachelor’s degree in political science from the University of Maryland and a law degree from Western Michigan University Cooley Law School. He grew up in Commack and is married and has three children. 

Mangelli said he “would make the Bethpage water plume my No. 1 priority.” The toxic plumes emanating from a Bethpage site where the Navy and the company now known as Northrop Grumman operated for decades are a “catastrophe,” and Mangelli said he would set up a special department to conduct further research on the plume. “I’m not going to worry so much on how to pay for it. I’ll get the funding to pay for it . . . The Town of Oyster Bay must do everything possible to make sure the drinking water is safe for us to drink and that Bethpage is safe to live in.” Mangelli said incumbent Joseph Saladino, appointed in January, “is not practicing what he preaches” in asserting he’s increasing transparency. He pointed to taxpayer-funded material that he said promotes Saladino and his campaign. “While claiming it’s a new day, it’s the same exact day because his administration is 100 percent controlled by the Republican power brokers,” he said. Mangelli, who works on debt consolidation cases as a lawyer, said the town’s debt needs to be restructured, and “we need to cut the waste, the fraud, the fat” out of the budget.

Ripp, 56, of Massapequa, is running on the End Corruption line. He declined to be interviewed.

Saladino, 55, of Massapequa, is running on the Republican, Conservative, Independence and Tax Revolt party lines. He was appointed Oyster Bay Town supervisor on Jan. 31, 2017, to replace former supervisor John Venditto. Previously, he served in the state Assembly from 2004 until this year. Before being elected to the Assembly, he was Oyster Bay’s director of operations. A former news broadcaster, Saladino worked for radio and television outlets across the region. He received a master’s degree in broadcast journalism from the New York Institute of Technology after receiving his undergraduate degree. Saladino is single.

Saladino said he wants to continue ethics reform in Oyster Bay. He said he is looking into ways to make the awarding of contracts and appointing of officials more public and open, modeled on the awarding of concessions agreements earlier this year that featured two days of livestreamed presentations and deliberations. “We’re looking at incorporating some of that into the process of publicly vetting candidates for inspector general,” Saladino said. He said he wants to continue the process of “right-sizing government” and “to bring about efficiencies in every department.” He said the town needs to reduce borrowing to cut its debt. In Hicksville, he said, he wants to see mixed-use development and a walkway modeled after New York City’s High Line that “complements our revitalization in downtown, where properties will be redeveloped.”
