So far, 2016 has not been a great year for political normalcy, musical icons or, of late, old presidents whose attitudes for their times don’t fit well with current mainstream ideals. The Treasury Department’s announcement last week that Harriet Tubman would replace Andrew Jackson on the front of the $20 bill was greeted by many as a long-overdue adjustment to modern thinking while serving as a tribute to the contributions of African-American women in American history. Tubman was an abolitionist during the mid-19th century who herself escaped from slavery, then conducted the Underground Railroad, risking her life to lead hundreds of slaves to freedom.
