ok, here are a few ideas...
I believe Andrew Jackson was not a good president because:
He lied to the Native Americans
He stole land from them and forced them to walk the 'Trail of Tears'
He supported the Plessy VS Ferguson case ( it ruled that African Americans were not people )
He killed multiple people to keep his 'good reputation'
When South Carolina began threatening secession, Jackson told a South Carolinian, "If a single drop of blood shall be shed there in opposition to the laws of the United States, I will hang the first man I can lay my hand on engaged in such treasonable conduct, upon the first tree I can reach."
