For good or ill, President Jackson is being brushed aside due to a campaign to have a female, preferably a minority to check multiple politically correct boxes as possible with one replacement, depicted on a US Banknote.
The choice for his replacement has been announced. In his place, Republican Anti-slavery activist Harriet Tubman to replace Jackson on $20 bill
No Lawyers, Only Guns And Money has a rather modest suggestion that I would also support - Have the depiction of Tubman on the $20 be one of her carrying the pistol she owned. Indeed, the vignette on the back of the bill could very well be the second picture in his post as suggested by Iowahawk on twitter.
