Palmer's win over Reiter, who has said he is under criminal investigation by the state Attorney General's Office for alleged misuse of town gasoline in personal vehicles during his tenures as supervisor and highway superintendent, sets up a Nov. 5 contest against Village of Lewiston Trustee Dennis J. Brochey Sr.
Brochey, the endorsed Democratic candidate, turned back the challenge of town finance director and former councilman Michael A. Johnson in a Democratic primary.
Complete but unofficial returns on the Republican side showed Palmer the winner over Reiter, 434 to 347.
The Democratic tally was 527 for Brochey, 250 for Johnson.
In a letter to voters during the campaign, Palmer, the former Niagara Falls and Youngstown police chief, said he will “stress ethical accountability. As supervisor, I can assure you, my administration will not be the subject of state and federal investigations.”
Reiter is in his fourth year as supervisor and before that was highway chief for 10 years. He underwent a quadruple bypass heart operation in early July.
The county Republican organization turned to Palmer after The Buffalo News disclosed in June that the FBI, which later turned the case over to the Attorney General's Office, had questioned Reiter about a variety of alleged improprieties.
Johnson said Reiter asked him to run for supervisor on the Democratic side “because you know more about the town than anyone else.”
However, the Democratic voters preferred Brochey, a longtime auto repair shop owner who was elected to the Village Board last year.

In the 15th District, covering Royalton and Hartland and a slice of the Town of Lockport, Joshua D. Walker edged GOP incumbent Michael A. Hill, 28 to 25, in a Conservative primary.

Mongielo, a former GOP committeeman who lost a supervisor race to Smith in 2009 and since has changed affiliation to Conservative, will be Smith's sole opponent in November, as the Democrats did not field a nominee.
For councilman, GOP voters preferred the incumbents, Mark C. Crocker and Patricia Dufour, over first-time candidate Paul R. Black.
Crocker polled 521 votes and Dufour 487, wrapping up new terms for them, since there are no Democratic candidates. Black received 228 votes.
Meanwhile, Republican Councilwoman Cheryl A. Antkowiak scored a sweep against Democrat John J. Ben in Republican, Democratic and Working Families primaries for town justice, a contest to replace the retiring Raymond E. Schilling. Antkowiak won the GOP race, 450 to 200; the Democratic race, 121 to 68; and the Working Families contest, 6 to 3.
Coleman garnered 296 votes and Neidlinger 272, while the 75-year-old Pettit trailed with 161.

Czarnecki picked up 135 votes and Harman 116, while Aimee A. Jarvis trailed with 101.
Czarnecki, 54, serves on the town's recreation committee and business development committee. She has been an administrator with the Buffalo Public Schools for more than 30 years.
Harman, 65, the retired supervisor of biomedical engineering at Erie County Medical Center, is finishing his first four-year councilman term.
In the Conservative primary for highway superintendent, incumbent Jeffrey R. Stowell crushed Aaron J. Bair, 40 to 4. However, Bair is the endorsed Democratic nominee for the November election. Stowell has held the post for 10 years.
Flint polled 180 Republican votes to 163 for Dewart, 39 for Carl A. Austin and 17 for Louis J. Mead. The GOP did not endorse any of the contenders, deciding on an open primary to choose a successor for Kenneth J. Bigelow, who decided not to run for re-election.
