(CNN) - Democrat Peter Shumlin was officially elected governor of Vermont Thursday in a joint session of the state legislature. He received 145 votes compared to 28 votes for the Republican nominee, incumbent Lt. Gov. Brian Dubie.
Though Dubie conceded the race shortly after the November 2010 election, the Vermont state constitution requires that the legislature elect the governor, lieutenant governor, and other statewide officials if no candidate receives a majority of the votes.
Shumlin, a state senator, received 49.5 percent of the vote in the November election, compared to 47.7 percent for Dubie.
Democrats control both chambers of the state legislature, with a 95 to 48 seat advantage in the House and a 22 to 8 seat lead in the Senate.
Shumlin will be sworn-in Thursday afternoon. He replaces outgoing GOP Gov. Jim Douglas.
