Brennan has an MA in govt? It was not youthful indiscretion. He knew what it was all about. Lots of people voted democrat when they were young, and then turned republican when they got older. If you voted communist when you were young, you may have already to far to the left to make that change.
Communists (and their kin) have murdered more innocent people than the Nazis, yet somehow both aren’t reviled equally by the Left....
