Treason must be made odious

"Treason must be made odious" was the most common shorthand rendering of a stump speech (a standardized campaign speech repeatedly made by a politician at a series of locations and times) made by Tennessean Andrew Johnson when he was military governor and a U.S. vice-presidential candidate in 1864. The phrase became relevant to the post-American Civil War legal issues surrounding the potential prosecution of former Confederate politicians and officers, as well as questions of enfranchisement of freedmen versus the re-enfranchisement of ex-Confederates. It has been described as "one of the best-remembered sayings of one of the least-remembered of our Presidents."
