Huey Long was a man of great ambition, one who used his personality to overcome any obstacle and help support his far-reaching populist goals. While I may disagree with the man who FDR called “one of the two most dangerous men in America.” (The other was Gen. Douglas MacArthur), You cannot deny that he has a flair that you are not fascinated with. The man was interesting, one for the ages, despite his authoritarianism.
Interestingly enough a Long Presidency probably would have eventually lead to a military coup led by MacArthur. And then 20th century American history proceeds much more like its neighbors to the south.
