Incumbent Supervisor Robert Cliffe staved off a challenge from candidate Thomas Larson in Tuesday's Republican primary.
Unofficial results from the Niagara County Board of Elections showed Cliffe defeating Larson 567 to 312.
The pair will meet again in the upcoming general election as Larson has the Democratic line. Cliffe is looking to secure his third term as supervisor this fall.
In the Republican primary for town board, incumbent Arthur Gerbec (525 votes) and Randy Retzlaff (547), nephew of outgoing councilman Kenneth Ratzlaff, secured victories over Larson's running mates, Michael Kislack (316) and Karen McKernan (320).
While Republicans had to decide both supervisor and council positions, Democrats hit the polls looking to choose its two council seats. Kislak and McKernan, however, were again defeated by Shirley Joy, chairwoman of the town Democratic Party, and Judy Blake. Unofficial vote totals had Joy collecting 297 votes, Blake receiving 274 and Kislack and McKernan securing 185 and 175, respectively.
Niagara County Legislature Chairman Bill Ross (380 votes) fended off challenger Sean O'Laughlin (208) in the Republican primary in the legislature's second district.
