My turn for Devil's advocate
Andrew Johnson is often considered the worst president ever. On top of being impeached, some are against his veto of various Civil Rights bills. While not going so far as to say he was good, I don't think Johnson is deserving of the title "Worst President Ever."
Johnson attempted very hard to continue the lenient terms of Reconstruction started by Abraham Lincoln. His plan was given very little chance, though, as the Radical Republican-controlled Congress wouldn't let him. Despite his best efforts to stop them, Congress placed the South under military rule and enacted harsh terms for Reconstruction.
Of course, the South did some things before having all power revoked. One of these things was the Black Codes, which severely restricted the rights of former slaves. To combat this, Congress put forth various Civil Rights bills. Johnson vetoed many of them. But his vetos were not born of racism, as is commonly thought, but of insistence that it remain a states issue. Also, this is where he chose to take his stand against the Radicals' harsh Reconstruction. Not the best place to do so, but at least he did it.
And, of course, most people assume he was awful because of him being impeached. But this was mostly a setup by the Radical Congress. Overriding Johnson's veto, they passed the Tenure of Office Act, which required Congressional approval of dismissals in the Cabinet. When Johnson attempted to fire outspoken Radical Secretary of War Stanton, he was impeached by Congress. Certainly didn't make it any easier for himself, but just as certainly not all his fault.
As a president, Johnson was not very good, mid to low thirties, really. But he is certainly not deserving of Worst President Ever. He really just had the unfortunate coincidence of being a moderate in a time of Radicals. Ironically, the Radicals enacted Radical Reconstruction to stop the South from being a Democrat powerbase. Not only did their form of Reconstruction cause this, it also led to the formation of the Ku Klux Klan.
So, after reading this, what do you say? Andrew Johnson: Worst President Ever or Victim of Circumstance?
