Arthur G. Pappas, a Republican, has been re-elected mayor of North Tonawanda, winning his first four-year term.
Pappas defeated Democrat James McGinnis by about 800 votes in complete but unofficial returns posted by the Niagara County Board of Elections.
Pappas was appointed mayor to replace State Sen. Robert G. Ortt in December 2014 and won an election for a two-year unexpired term in November 2015.
Pappas' opponent in 2015 was Democrat John Tylec, and on Tuesday Tylec's son Austin Tylec became the only elected Democrat in City Hall. He swamped former County Manager Jeffrey Glatz, the Republican, by more than 1,000 votes to win the alderman at-large seat.
However, the three ward aldermen, all Republicans, each seem to have narrowly survived strong Democratic challenges.
