YORKTOWN, N.Y. -- Susan Siegel looks to be the newest member of the Yorktown Town Board, though her opponent refuses to concede.
According to unofficial election results from the Westchester County Board of Elections, Siegel leads Tom Diana 5,543 votes to 5,414 votes, 51 percent to 49 percent, with 100 percent of the vote counted.
Siegel, a Democrat and former town supervisor, and Diana, a Republican, were running to fill the seat left vacant when Dave Paganelli was elected highway superintendent.
Diana said due to absentee ballots yet to be counted, he was not ready to concede. Diana said machines have also been impounded due to a major glitch and a recount might occur.
"We're going to wait and see what happens," Diana said. "It's that close. I ran a good campaign and met great people. I hope I am given the opportunity to serve them.
Siegel said she was cautiously optimistic that she was elected.
"I'm very encouraged and very positive," Siegel said. "I'm looking forward to serving and bringing back civility to the town board."
The former supervisor said the town has to start moving forward and doing a better job. She hoped the election results would be certified in time for her to vote on the town's 2015 budget.
Siegel, who has often been at odds with Supervisor Michael Grace said she feels comfortable working with him.
"There are things he has proposed I can fully support," Siegel s said.
The Town Board still has to fill the vacancy left by the recent resignation of Councilman Nick Bianco and will have to fill another vacancy following the election of Terrence Murphy to state senate.
Absentee ballots will be counted on Nov. 12.
