The only competitive races for local offices in Niagara County in Tuesday’s election are contests for town justice in Porter and Royalton.

In Porter, Republican Wayne D. Pollow faces Democrat Patrick F. Stack for the post being vacated by retiring Justice Walter C. Holmes. Pollow, a fire police lieutenant in the Ransomville Volunteer Fire Company, won all four minor party lines in the Sept. 13 primary against Stack, a Niagara Falls police detective.

In Royalton, three candidates are seeking the post last occupied by Margaret M. Raduns, who died March 19.

Laura A. Wagner, an attorney for the Niagara County Social Services Department making her first run for elected office, has the Republican, Working Families and Green parties’ lines. Town Councilman James G. Budde, a member of the Independence Party, has the Democratic and Conservative lines, while former Justice Deborah A. Carpenter appears on the Independence line. She and Wagner are Republicans.
