The 1780 Connecticut gubernatorial election was held on 13 April 1780 in order to elect the Governor of Connecticut. Incumbent Nonpartisan Governor Jonathan Trumbull won a plurality of the vote in his re-election bid against other candidates. However, as no candidate received a majority of the total votes cast as was required by Connecticut law, the election was forwarded to the Connecticut legislature, who chose Trumbull as governor.[1]
On election day, 13 April 1780, incumbent Nonpartisan Governor Jonathan Trumbull won re-election after having been chosen by the Connecticut legislature. Trumbull was sworn in for his fifth term on 10 May 1780.[2]
