CHARLEMONT — While Stephen W. Thayer is the sole ballot candidate seeking election to a two-year Selectboard term, Kim Alison Blakeslee is challenging him with a write-in campaign.

The victor in Tuesday’s election will fill the seat vacated by William Harker, who resigned. Polls will be open from noon to 7 p.m. at Hawlemont Regional School.

During a Pre-Town Meeting Information Session and Candidates Night held at Hawlemont on May 22, Thayer described himself to voters as a “straight shooter” who grew up in Charlemont and has moved back to town.

“I come from a long line of people who have served,” he said. “I don’t have an agenda. “I just want to look out for the taxpayers’ money.”

Thayer said he lived in Colrain for 30 years and served on the Board of Commissioners for Fire District I.

“I understand how small-town politics work,” said Thayer, who owns Heritage Diner at 90 Main St. “I want to see the town stop looking at today and see what’s coming, and to really take the future more seriously, [regarding] police, fire and ambulance. It’s time to have serious discussions about regionalization.”

Blakeslee was born in Charlemont and attended Hawlemont and Mohawk Trail regional schools. While her two daughters attended those schools, Blakeslee was active on Hawlemont’s Local Education Council and the Parent-Teacher Organization. She has also been a member of the Friends of the Charlemont Fairgrounds and organized one of the Yankee Doodle Days. More recently, she co-chaired the Charlemont 250th Committee, raising money over three years for the town’s anniversary celebration.

For the past 14 years, Blakeslee has worked in family support services for Clinical & Support Options (CSO) of Greenfield, helping people with behavioral and mental health issues find housing, address food insecurity or get parenting education. She said she is also skilled in working with government systems.

“Although [the Selectboard] will be a big learning curve for me, I feel I could hit the ground running,” she said. “I believe in civic duty.”
