As a democrat and Presbyterian, I have long tried to admire Oliver Cromwell. I once had an argument with his statue outside the Parliament building, going over his pros and cons. I think he did assist the cause of Reformation of the Church of England. On the other hand, his suppression of Parliament was a setback to the cause of republicanism in Britain for centuries, and his brutal treatment of Catholics is just unpardonable.
As a Democrat and Presbyterian, I have long tried to admire Andrew Jackson. I believe he is mostly a positive figure, and his refounding of the Democratic Party has been a hugely beneficial gift to the nation. On the other hand, his destruction of the Bank set back the national economy for generations, and his brutal treatment of the Indians is just unpardonable.
Still, Jackson's excesses were constrained by the presidency, which he respected and left voluntarily. Cromwell's excesses just grew and grew and were constrained by nothing but death.
So here is one cheer for Andrew Jackson. Cromwell will have to be content with his statue.
