If candidates can be judged by the company they keep, David Lys will be difficult to beat. Aside from winning a lopsided victory over David Gruber in a September primary, he has been vouched for by, among others, Perry B. Duryea III, former town Republican chairman; Alex Walter, a former zoning board chairman who was Supervisor Larry Cantwell’s assistant; Zachary Cohen, a former town supervisor candidate; Tim Taylor, the head of Citizens for Access Rights, and nearly the entire town Democratic power structure and many Republicans alike.
