The 1863 Maine gubernatorial election took place on September 14, 1863 in order to elect the governor of Maine.[1] Republican candidate Samuel Cony won his first one-year term as governor[2] against Democratic candidate Bion Bradbury.[3]
During his campaign, Bradbury claimed that president Abraham Lincoln had violated the Constitution by suspending habeas corpus, and was a vocal opponent of emancipation.[5] While a controversy occurred where General Samuel J. Anderson[6] claimed in an interview that Bradbury would withdraw Maine's troops from the American Civil War, Bradbury denied this and accused Anderson of libel.[7]
