Andrew Johnson grew up in a very poor family in North Carolina, and later Tennessee. His family was considered "white trash" and he held a lifelong grudge against those who he considered upper-class. However, he went out of his way to give assistance to old friends and to men of humble means. While he was reserved, he possessed a powerful speaking voice and was respected as an orator. His profane temperament and self-importance ensured his isolation as President -- a situation that Johnson exacerbated with his obstinacy in the face of overwhelming Congressional opposition.
You are also similar to Ulysses S. Grant.
Ulysses S. Grant was raised in southern Ohio in a poor family. He used the Army to escape his origins. He was a quiet, often irascible man. Yet he was a very hard worker, and a diligent taskmaster. He was also a hard drinker and smoked several cigars a day. While he was personally ethical, his associates were embroiled in an embarrassing number of scandals during his time as President. He had a number of strange personality quirks and superstitions. Grant was not refined or worldly, but his performance during the Civil War leaves absolutely no doubt as to the brilliance of his mind.
You are also similar to John Quincy Adams.
John Quincy Adams was the son of President John Adams, and thus was never lacking for material comfort or connections. However, much like his father, he was naturally lacking in social charm and was quite withdrawn. He himself admitted that he was overly set in his ways and personality. Yet he was studious and hard working, and even after his Presidency remained involved in public life for many years. Adams was prone to anxiety, depression, and mental instability, and even expressed suicidal ideation on a couple of occasions. He could never shake rumors that he had made a "corrupt bargain" to win the Presidency from Andrew Jackson in 1824.
You are least
similar to Franklin Pierce.
Franklin Pierce was born to a family of comfortable means in New Hampshire. He was confident and outspoken, yet sometimes a bit too eager for the approval of others. He was a heavy drinker for most of his life, eventually dying of cirrhosis. His family life was also marred by tragedy. As President he tried to administer efficiently, dividing appointments amongst numerous competing factions of Democrats. Besides his drinking, there were few hints of ethical impropriety. Pierce was well-traveled, but rather myopic and narrow in his worldview. In spite of his New England roots, he consistently blamed northern abolitionists for the start of the Civil War.
