Don't forget Whittaker Chambers. :-) Lots of leftists act like Alger Hiss came out of nowhere to become the archetypal Poor Persecuted Progressive, but the road to truth begins when you understand how and why Chambers made him (in)famous.

Alger Hiss was totally communist, a plant, and you are right.

"Don't forget Whittaker Chambers"

"Witness" is a fantastic book that everyone should read. I would also include Richard Nixon because of his role in bringing Hiss to trial - the Communists never forgot and Watergate gave them the opportunity for revenge.
