Elections for the Vermont State Senate will take place in 2024. The general election is on Nov. 5, 2024. The primary was Aug. 13, 2024. The filing deadline was May 30, 2024.

All 30 seats are up for election. Democrats hold 21 seats and Republicans hold seven.

Vermont is one of 29 states where one party has large enough majorities in both legislative chambers to override gubernatorial vetoes without needing support from members of the other party. Democrats need 20 seats in the Senate in order to override gubernatorial vetoes. If Republicans gain more than one seat, they will break the Democratic veto-proof majority. If Democrats do not lose more than one seat or gain seats while also maintaining a 100-seat majority in the state House, they will maintain their veto-proof majority.

Since his election in 2016, Gov. Phil Scott (R) has vetoed 52 bills, more than any other governor in state history, according to Seven Days. The majority-Democratic legislature has overridden six vetoes in 2024, surpassing the previous record of five vetoes set in 2023. The legislature’s 2024 overrides included vetoes of bills requiring state utilities to provide energy from renewable sources only by 2035, prohibiting the sale of seeds treated with certain pesticides, and increasing property taxes.

This election will also determine Vermont’s trifecta status. Vermont is one of 10 states without a state government trifecta because the governor is a Republican and Democrats have majorities in both chambers of the state legislature. The governorship and the entire Legislature are both up for election this year. If one party wins the gubernatorial election and majorities in both chambers of the legislature, that party will gain a trifecta in Vermont. A mixed result would maintain the state’s divided government.

Ballotpedia identified four districts with a combined seven seats as battleground districts. Democrats and Republicans hold three seats each in the battleground districts. The seventh seat is vacant. Three of the four battleground districts have at least one incumbent who is not running for re-election. As of Oct. 23, 2024, CNAlysis rated four of the seats in battleground districts as favoring Democrats and three as favoring Republicans.

The Vermont State Senate is one of 85 state legislative chambers with elections in 2024. There are 99 chambers throughout the country.
