In an interview Thursday, Kaiman, 50, said the constant campaigning -- the town supervisor's job is a two-year term -- and intensity of his current position led him to seek his previous role as district court judge.
"Being a district court judge is a great job," said Kaiman, who was appointed to that post in 2000 and elected to the position that same year before becoming town supervisor in 2004. "I believe my 10 years as town supervisor has run its course. It seemed appropriate to go back and finish the job that I was doing" at the court.
Kaiman's name had come up repeatedly in recent months for intensely public positions -- first for a top post at the Long Island Power Authority, then later when he explored a bid for Nassau County executive.
"That was just one of the many directions that I thought I could take," said Kaiman, who holds a law degree from Hofstra University. "I'm not retiring. I'm not riding off into the sunset. This is another opportunity."
Kaiman, who said he would finish his term, expressed support for Bosworth, who said she hoped to continue the line of Democrats who have led the town for two decades.
"I know that I can bring my own style, background, experience and substance to the job," she said. "I think it's a job that can really suit my skill set."
Bosworth, 65, said she hoped to tackle environmental issues, such as protecting the aquifer and drinking water, and said she was looking forward to presenting her governmental record to voters. In addition to serving in the legislature for six years, Bosworth served on the Great Neck school board for 16 years.
"I'm looking forward for residents to have a chance to compare my record of leadership with my opponent's," she said.
Republican supervisor candidate Dina De Giorgio, who has served on the town board since 2012, said Kaiman's bid for a district judgeship "seems like a step down for him," and said she welcomed the fight for the supervisor's seat.
"Judi has absolutely no experience in town government. She's not a lawyer," De Giorgio said. "I think I'm the better candidate."
Wink, 46, a former North Hempstead Town councilman who was elected to the legislature in 2007, said he liked the idea of a return to town-level government.
"For me, it just seems like a great fit," said Wink, who until Tuesday had been a contender for Nassau County comptroller. "We're at a point now where tickets are being formulated and people are coming down to decision-making time, and this, I think, is the right decision."
Wink faces incumbent clerk Leslie Gross, a Democrat who announced this week she was running for re-election on the Republican line.
The Democrats will run former town public information officer Sidhartha Nathan, 27, against Republican town councilman Angelo Ferrara, 68.
