It’s a year of change in Vermont politics, with the governor, lieutenant governor and attorney general all stepping aside. And a mainstay in the legislature is leaving, too. Bill Doyle began serving in the Vermont Senate in 1969 and is the longest-serving senator in the state’s history. But the 90-year-old Republican lost his re-election bid this year. On November 30th, he withdrew his request for a recount and conceded the race. Doyle says activity in the statehouse become more political over the years.
