The media and Hollywood have NEVER stopped smearing this guy...even though his allegations focused on Communists and Communist sympathizers well known at the time:
• Didn’t Truman have Communist sympathizers close to his administration?
• Wasn’t Hiss exposed?
• Didn’t Acheson continue to support Hiss?
• Wasn’t a DOJ employee selling defense secrets?
There were lots of questionable people and activities he wanted to expose.
McCarthy may have been disagreeable, personally, but his message was direct. He wanted to open a hole and drive a truck through it. Truman was being un cooperative and turned it into a partisan issue. Liberals have been doing the same ever since.
Most people think that McCarthy blacklisted Hollywood people. Actually McCarthy had nothing to do with Hollywood. There were separate investigations in the House and the Senate. It serves the propaganda media and the left in the USA to keep people believing that McCarthy investigated Hollywood.
