Democrat Becca Balint would become the first woman elected to the U.S. Congress from Vermont, U.S. broadcasters have projected.
Vermont, from the north-east of the country, was the last remaining U.S. state not to have elected a woman to Congress.
Balint defeated Republican nominee Liam Madden and took over from Republican Peter Welch.
Welch, a Democrat, was elected to represent Vermont in the Senate, replacing long-serving Patrick Leahy.
Leahy, 82, was first elected to the Senate in 1974 and didn’t seek re-election.
