Well if Joe was wrong about anything it was he grossly underestimated the number of communists in the State Department and again thanks to the left, the state department is still a haven for communists waiting for the progressives and their useful idiots to collapse the system so they can step right in without firing a shot.
It is amazing the hollywierd types that still rail against Joe when it was HUAC not the senate but the leftest scum in Hollywood are not that sophisticated as to understand the difference.
The Left lost when they took on the Nixon, Chambers, Valtin, Kravchenko, Koestler, Orwell and countless others who for years had hammered away all credibility the Communist and their fellow travelers had with the American public.
So after the Left had already lost the battle, they adapted McCarthy as the villian for their complete rewrite of history and brainwashing of subsequent generations.
CORRECTION: adapted = adopted
