BOW, N.H. — Kevin Cavanaugh has won the special election for New Hampshire’s District 16 state Senate, becoming only the second Democrat to win the seat since 1976.

Cavanaugh defeated Republican David Boutin and Libertarian Jason Dubrow on Tuesday.

District 16 covers Bow, Dunbarton, Candia, Hooksett and parts of Manchester. The seat was left vacant by the death of Democrat Scott McGilvray in March.

In a statement Tuesday night, Senate Democratic Leader Jeff Woodburn said Cavanaugh delivered “a positive message about rewarding work and standing up for working families.”

The New Hampshire Democratic Party says Cavanaugh’s win marks the first time New Hampshire Democrats have won a state Senate special election since February 1984.

Cavanaugh will serve as the 10th Democrat in the 24-seat state Senate.
