Anaconda, 19th Day of Hagwinter, 525 M.E. (Helios): At the end of his term, the worst president in U.S. history refused to attend the inauguration of his successor. Instead, he stayed and sulked in the White House, and then quietly slipped out without notice or fanfare.

The worst president was openly racist, had a terrible personality, and was extremely insecure. He had no curiosity at all, no understanding of how the world worked or what other people's lives might be like. All he wanted was to amass power. He made his cabinet swear loyalty oaths, and those who didn't were summarily fired. 

When asked if there was anyone in politics he didn't like, the worst president admitted that he had an enemies list. He claimed, without evidence, that two members of the opposition party were plotting to kill him, and his supporters viewed the accusations as a declaration of war. 

The worst president purged government agencies of those he deemed disloyal and replaced them with loyalists who would do his bidding. On Washington's birthday, he gave a long, rambling speech that lasted over an hour and only mentioned Washington's name a handful of times, but mentioned his own name over 200 times.

He was so bad, the worst president in U.S. history was impeached by Congress, although he survived conviction by a single vote. And so Andrew Johnson, the 17th President of the United States of America, the man who assumed the office as a result of Lincoln's assassination, was able to finish out his term. Who'd you think I was talking about?

He was not a charismatic man. When Lincoln picked him for vice president, the New York World opined, "To think that one frail life stands between this insolent, clownish creature and the presidency! May God bless and spare Abraham Lincoln!" 

An open racist, Johnson was quoted as saying, "This country is for white men. And by God, as long as I'm president, it shall be a government for white men." His actions were true to his words. He made it easier for Confederate states to come back to the Union without first guaranteeing equal rights for Blacks. After Congress passed the Civil Rights Act of 1866 and created the Freedmen's Bureau to assist the former slaves,  Johnson vetoed the bill, although Congress was able to override his veto. Johnson responded to the override by replacing the Freedmen's Bureau personnel with his own loyalists. His impeachment was for firing War Secretary Edwin M. Stanton without the consent of the Senate, although Stanton had been appointed with the Senate's consent.

In 1865, General William T. Sherman's Special Field Order No. 15 had designating the entire Southern coastline 30 miles inward for exclusive settlement by former slaves. Freedman could settle there, taking no more than 40 acres per family ("40 acres and a mule"). By June of that year, 40,000 freedmen had moved onto new farms in the area, but in August, Johnson returned the land to the Confederate owners, and the freedman were forced off, same at bayonet. 

Historian Glenn Lafantasie notes Johnson is frequently a favorite candidate for historically worst president because of "his complete mishandling of Reconstruction policy  . . . his bristling personality, and his enormous sense of self-importance." Another said that "Johnson is now scorned for having resisted . . . policies aimed at securing the rights and well-being of the newly emancipated African-Americans." In short, it's generally agreed that Andrew Johnson scuttled the Reconstruction and initiated nearly 100 years of Jim Crow.     

If any of his traits and actions sound familiar, like his ignorance and lack of curiosity, the loyalty oaths and list of enemies, removing Senate appointees without due process, his egocentricity, his paranoia, his racism, his vindictiveness, and the impeachment, you're drawing parallels between the Stable Genius and the worst president in U.S. history (so far).

Except the Stable Genius was impeached twice (so far).
