Some historians may argue that Andrew Johnson hurt his own presidency by not working with the Republican congress and brought on his own downfall. However, that particular viewpoint has only gained popularity in couple of decades. The first wave of historians that evaluated the Reconstruction period showed much sympathy for Johnson.
As Johnson did not run for President in 1868, there are not many campaign songs that were written in his favor. American Pioneer Music has put together a vocal sketch of a song included in a Horatio Seymour songbook, which was part of his losing campaign against Grant.
Fans of Civil War Music will recognize the tune as "Grafted into the Army," as popular anti-war song written by Henry C. Work.
