The man had the capacity to inspire - most importantly - the young. That's not to be dismissed. He was a leader.
As to which leaders deserve our admiration.
I'm sure you've noticed that many are completely forgotten soon after they leave power - William Henry Harrison, Tyler, Grover Cleveland, McKinley. The list is long. Only historians and partisans remember them.

Where? Where did he lead us?
