High school junior David Oks works on his mayoral campaign after school, when he's done with his homework. The 16-year-old has a chief of staff, a communications director and a data director on his campaign staff. Most are high school students at the private Masters School in Dobbs Ferry, N.Y.

The aspiring mayor didn't get enough signatures to appear on the Nov. 7 ballot, so he's running as a write-in candidate.

If he had collected enough signatures, the Board of Elections in Westchester County said, he would have appeared on the ballot.

"New York election law doesn’t require you to be registered to vote to run, which would be the only way we could check your age," said Tajain Nelson. "We don't know the age of anyone who runs for office." It's not required on the application, she said. 

Oks said the Board of Elections sent his campaign the list of their town's registered voters, so they could canvas. He's running as an Independent and said it is a real campaign that Democrats could support. "It's a platform that talks about the rights of immigrants, disabilities, about the Paris Agreement," Oks said. "It's a very liberal platform."

Oks is in Model U.N. And he's a Boy Scout, who competes in history competitions. He got the idea to run for mayor from New Jersey Sen. Cory Booker. They met this summer when Oks worked as a page in the U.S. Senate. "Sen. Booker told me the best way to get involved in politics is to run for office," he said. 

In Ardsley, being mayor is a part-time job.

"So I think I could definitely handle it along with my current school work," Oks said.
