The 1846 Rhode Island gubernatorial election was held on 1 April 1846 in order to elect the Governor of Rhode Island. Law and Order nominee and incumbent Lieutenant Governor Byron Diman defeated incumbent Democratic Governor Charles Jackson. However, as no candidate received a majority of the total votes cast as was required by Rhode Island law, the election was forwarded to the Rhode Island legislature, who chose Diman as Governor.[1]
On election day, 1 April 1846, Law and Order nominee Byron Diman won the election by a margin of 86 votes against his opponent incumbent Democratic Governor Charles Jackson, thereby gaining Law and Order control over the office of Governor. Diman was sworn in as the 19th Governor of Rhode Island on 6 May 1846.[2]
