Clement Vallandigham, an Ohio opponent of the Civil War and of abolition, was thrown out of the country by Abraham Lincoln because of his political views. As a result of his banishment, Vallandigham became a martyr to his cause and was nominated for governor by the Democratic Party in 1863. He ran the race from exile. The stakes in this colorful campaign were enormous, and Lincoln was highly involved, worrying that a Vallandigham victory would be seen as a rejection of the war by voters. That could have been devastating to the Union cause. It also would likely have made Vallandigham—a former congressman from Dayton—a presidential prospect. This book tells the story of a unique event in American history: a president—significantly, Lincoln—banishing a leading opponent, with that opponent then being nominated by a major party for high office in an important state.
