The people have spoken — at least, the people who cast ballots in an unofficial "Women on 20s" campaign — and more than 100,000 voters want to see Harriet Tubman on the $20 bill instead of Andrew Jackson. Tubman, the abolitionist who helped free slaves on the Underground Railroad, on Tuesday was declared the winner of an online poll, part of a petition aimed at convincing the Treasury Department to put a new face on the $20 — and specifically a female one.
