Has to be Woodrow Wilson. Racist, suppressor of free speech. The prototype of the academic elitist type.
I find it interesting that Grover Cleveland, the last great president which the Democrat party produced, was a Princeton Trustee post presidency and he absolutely could not stand Woodrow Wilson.
Woodrow Wilson was the worst President by far. First, he is responsible for the Sixteenth Amendment (Income Taxes), and second, restoring the Federal Reserve, after Andy Jackson spent 8 years fighting to get rid of the Central Bank. No other President comes close to the damage Wilson did.
