So yeah, that happened. Harriet Tubman, the person who ran the "underground railroad" which served as a way for slaves to escape the south and head to the north before and during the civil war, is slated to replace President Andrew Jackson as the face on the 20 dollar bill. Andrew Jackson is known for helping to found the Democratic party. Fighting in the war of US secession from England, as well as against the native Americans, and for being generally obstructionist to politics and more then a bit spiteful.
