MONTPELIER, Vt. — Vermont Gov. Phil Scott, a Republican, won a sixth two-year term on Tuesday, turning back a challenge from Amanda Janoo, an economist making her first run for any office, WCAX and The Boston Globe reported.

Janoo, who ran as both a Democrat and a Progressive, conceded shortly before 11 p.m. in a speech to supporters gathered at her election night party in Burlington, both outlets reported. Scott claimed victory soon after at his own party in Montpelier.

With roughly 95% of the vote tallied, Scott had 52.2% and Janoo had 46%, the Globe reported, citing The Associated Press. Those figures are unofficial.

The outcome came after polling before the election showed the two candidates running about even, according to WCAX, which described the contest as the most competitive race for Vermont governor in a decade.

If Scott completes the new term, he will have held the office longer than anyone since Vermont became a state, the Globe reported. The Globe said the current mark belongs to Howard Dean, who served as governor for 11 and a half years.

Janoo had never before sought public office, according to both outlets.
