And yes, there were damned RINOs back then as well, who were anti-Nixonians. They and the lefties NEVER stopped harassing him and doing EVERYTHING they could ( including trying to make Ike ditch him, as his running mate for Ike's second term ! ) to trash/get rid of him.
The idiotic beginnings of that failed impeachment took just about THREE decades.

Personally, I think there were excesses in the HUAC hearings, but on the other hand, most of those people identified as Communists actually were Communists and were either actively working for the Soviets or were enabling Communism as fellow travelers (although I think useful idiots may have been a better term). Then as now, except that Russia finally saw the light - but Communists in the US are still Communists, no matter what they call themselves.
