Online poll wants Harriet Tubman as the new face of the U.S. $20 bill

Harriet Tubman should be the first woman on the $20 bill, according to a new online poll.

The survey was conducted by the advocacy group Women on 20s, which is pushing to have a woman's face on U.S. paper currency.

The organization sent President Obama a petition Tuesday asking him to push for the change.

The campaign has drawn a lot of attention. More than 600,000 people have cast votes in the online poll in the past ten weeks, including celebrities like Susan Sarandon and Ellen DeGeneres.

Harriet Tubman, an abolitionist who led slaves to freedom on the Underground Railroad, would replace Andrew Jackson on the $20 bill.

Tubman beat out a list of 15 candidates, including former first lady Eleanor Roosevelt, civil rights activist Rosa Parks, and Native American chief Wilma Mankiller.

Wikipedia wrote:Born into slavery, Tubman escaped and subsequently made about thirteen missions to rescue approximately seventy enslaved family and friends,[1] using the network of antislavery activists and safe houses known as the Underground Railroad. She later helped John Brown recruit men for his raid on Harpers Ferry, and in the post-war era struggled for women's suffrage.
