Michigander is one of the unofficial terms used to describe a resident of the U.S. state of Michigan. The term “Michigander” is attributed to Abraham Lincoln, who is said to have invented the word in 1848 in reference to Lewis Cass, the governor of the Michigan territory at the time. Lincoln opposed presidential candidate Cass and his campaign platform of “popular sovereignty,” which would allow states that had been conquered in the Mexican-American War to decide whether they wanted to make slavery legal. Abraham Lincoln referred to Lewis Cass as a “Michigander” in a speech, in an attempt to portray Cass as a foolish goose, or gander. Because of its origin, some Michigan residents view the term as offensive, although many do not. A 2011 poll showed that 58% of Michigan residents prefer the term Michigander over other Michigan resident terms such as Michiganian, Michiganer, Michiganite, Michiganese, and Michigine.
