Could it happen here? It is happening here.

My field of study in graduate school was communism. As a fellow at the Russian Institute of Columbia's School of International Affairs, I was, if I remember correctly, one of seven students in the entire university to major in what was known at the time as "Communist Affairs."

I cite this in order to make this point: In my wildest dreams, I never imagined what I was studying would ever apply to the United States of America, the freest country in world history.

I assumed that communism was, for various reasons, something that happened elsewhere -- most obviously, Russia, China, Vietnam, Cuba, Cambodia and North Korea.
