Which of these four women should be on the $20 bill?

The group pushing to replace Andrew Jackson on the $20 bill with a woman has narrowed its field of candidates to four.

The group called Women on 20s has been pushing for the change, saying women in general deserve the recognition and that Jackson in particular is a controversial choice.

The group has winnowed the finalists from an original list of 100, in part through 256,000 votes cast by the public over the past five weeks.

Making the change would be surprisingly easy. It does not take an act of Congress; the Treasury secretary can choose who appears on paper currency.
