Oyster Bay Town Councilwoman Rebecca Alesia has been elected to the seat she was appointed to in February.
Alesia soundly defeated her Democratic opponent Donna Lee by a 64 to 36 percent margin, with 100 percent of precincts reporting.
She garnered 52,680 votes compared to Lee's 29,797.
Alessia, who lives in Plainview, is a former Nassau County Assistant District Attorney, who also has a background in zoning and land use.
She lost a race for the Nassau County legislature in 2009. In her few months on the Council, Alesia helped establish the new farmers market in Hicksville.
Lee, who's from Bayview, has worked in the real estate and mortgage business for 25 years. She is a longtime member of the Oyster Bay Rotary Club and is very active in the annual Oyster Festival. She touted her experience as a businesswoman during the campaign.
Despite losing, Lee said she felt, " terrific about the process."
"I wouldn't change a thing. I'm sorry I got into it do late, but I'm a Democrat going against the Oyster Bay machine."
Lee wouldn't immediately say if she would run for office again in the future.
