Personally, I do not want Jackson taken off of the twenty. I think he should be kept on the front, to be honest. I am all for adding diversity to our currency, honoring those who have not sat in the Oval Office or played a role in our country's founding. But Jackson, for all his shortcomings, did a lot of good for our country. Should we be taking Washington off of the $1 because he owned slaves? Should we take Jefferson off of the nickle? In twenty years will people point out some dubious comment Tubman made and folks will clamor to remove her from the $20? This whole thing feels like they are punishing Jackson and trying to retroactively paint a negative perception of his legacy. I have noticed this trend in recent years and I maintain that Jackson is a top tier President, no matter how unfortunate and misguided the Trail of Tears was (it should also be noted that a good many historians, a majority even, consider the Trail of Tears to be a good thing, because the alternative would've been inevitable, all out war, which would've ended in genocide for the Native Americans...Jackson picked the best of two bad options).
Also, I am a little irked by this because I believe we are overlooking deserving presidents simply because they are white men. Neither of the Roosevelts, Adams, Madison, JFK, Eisenhower, Reagan, Lyndon Johnson, or Truman have been placed on regularly circulated paper money. Its almost as if, despite their amazing contributions to our country and the world, they are disqualified merely on the grounds that they are white men. That just doesn't sit well with me.
Maybe I am old school, but I think the face on a bill should be reserved for only our founding fathers or the President of the United States. I believe that Tubman, MLK, Susan B. Anthony, etc should all be honored on the back of the bill. But in terms of the face on the front, I want it to be POTUS or a Framer.
