Flower of Iowa was a well researched novel set during WWI, that shed light on the horror of that war, and touched on how terrible the Spanish flu. Terrible times.
I take exception to the article focusing on Hoover, since Harding and Coolidge were the true numskulls that set up the US for economic depression.

Historians have not been kind, as opposed to a recent scandal ridden President that is still called the great communicator and has an as airport named after him.
Since the Spanish Flu and the Espionage Act were past events, his focus on Hoover baffles me.
Let's pay attention and hope Congress doesn't invent a modern version of the Espionage Act. Sounds like a couple of initiatives are currently in play, including iron handed oversight over digital messaging, such as this forum
