The 2016 United States Senate election in Vermont was held November 8, 2016, to elect a member of the United States Senate to represent the state of Vermont, concurrently with the 2016 U.S. presidential election, as well as other elections to the United States Senate in other states and elections to the United States House of Representatives and various state and local elections. The primaries were held August 9.
Incumbent Democratic Senator Patrick Leahy, the most senior member in the Senate, the longest-serving U.S. Senator from Vermont, and the first Democrat to be elected to a Senate seat in Vermont, won re-election to a record eighth term in office.[1]
This election was the last in which Diamondstone ran prior to his death in 2017. Diamondstone had run for Vermont statewide office in every biennial election since 1970.
