BTW, the info about Samuel Dickstein at that link was quite telling. Lots of Soviet moles in the HUAC, and they succeeded in bringing it down.
Another name that too often flies under the radar and is mention in that link is Frances Perkins.
In addition to smearing the work of the HUAC, as Martin Dies pointed out, she was responsible for the minimum wage laws which have crippled American business since their enactment. Of course, FDR is a name well-known and rightfully despised by anyone who truly loves America and our God-given liberty. But it was his so-called "brain trust" that implemented (and often conceived) the programs that led to the socialism of the New Deal. I have done a lot of research concerning her and I don't say this lightly, but Frances Perkins may truly be among the most evil women of the 20th Century.
