Reagan should be above Truman and possibly even Jackson. I am trying to remember exactly what Jackson accomplished. I know he was very effective but my memory does not serve me well right now.
I wish someone would explain Jackson. From what I remember, he was the first, non-elite, wealthy type guy to become President. I imagine he had huge battles with Congress, and he was, unjustly, almost impeached. Maybe it was a "for the people" attitude?
