ok, allow this poor ignorant (but suspicious) wretch to take a wild shot at the pot:
If I were to Google up the term(s) of Senator McCarthy and compare them with the dates between which the HUAAC was active, would I discover that they were not concurrent?

[nunya bidness]

It's my understading that HUAC overlapped the time when McCarthy was active on the Senate side. But the fatal mistake that most on the left (especially in Hollywood and the media) make is that they attribute McCarthy with HUAC. Ann Coulter's book Treason is an excellent source for this era.

[King Prout]

HUAAC: 1945-1969 (to 1975, under a new name)
Tailgunner's terms: 1947-1957

well, they are concurrent.

[SAJ]

They might be, but McCarthy was a Sinator (no typo), and had nothing to do with HUAC.

"DING DING DING! What do we have for her, Johnny?"

You hit the nail right on the head, mostly. His term began in 1948 or something like that, but his activities did not begin until later. There was no overlap in his activities and HUAAC's activities...
