A recount is set Monday to determine the winner of the third seat on the Board of Selectmen, an outcome that will decide which political party controls the panel.

In the aftermath of Tuesday’s municipal election, a 68-vote margin separates incumbent Democrat Sheila Marmion and Chris Tymniak, the Republicans’ first selectman candidate, with Tymniak in the lead.

While Tymniak lost the first selectman race to incumbent Democrat Michael Tetreau by nearly 800 votes, under Fairfield’s election laws, the next two top finishers among the four candidates for the Board of Selectmen — regardless of their political party — are elected.

In that case, the next highest vote total was posted by Republican Laurie McArdle, Tymniak’s running mate, with 7,629 votes, followed by Tymniak with 7,283 and Marmion with 7,215.

Official voting results will not be certified until after the recount. While attempts to reach Town Clerk Betsy Browne were unsuccessful Wednesday, Tetreau and Republican Town Committee Chairman James Millington both confirmed the recount is planned.

Millington said the GOP is “anxiously awaiting” the recount results, while his Democrat counterpart Heather Dean said her party is “cautiously optimistic” Marmion will retain her seat on the board.

If both McArdle and Tymniak are ultimately certified as the winners of the two selectman seats, it would give the GOP effective control of the board, while Democrat Tetreau would still be the top town executive — the first time that has happened since 1981 in the last election won by Democrat John J. Sullivan.
