Why was Joseph McCarthy a hero?

Answer 1

what party did senator McCarthy feel was a major threat to the United States government

In 1950 anti-communist hysteria began to emerge in the USA as encouraged by the actions of Senator Joe McCarthy who began accusing high-ranking US officials of being communists or at least them selling secrets to the Russians. Many government employees were found guilty about passing on secrets about the Atom Bomb but he eventually lost popularity and then soon power as his accusations grew wilder and cruder each day. All this simply served to increase tension between the two superpowers due to the hysteria created and the detest shown by this senator towards the communists.

Answer 2

Senator Joseph McCarthy claimed that there were known communists in the State Department. He claimed he had a list of them but he never made the list public. He held investigations and hearings and accused people of being communists or "fellow travelers." He ruined many careers. Presidents Truman and Eisenhower so feared his influence with the public that they did nothing to stop him. When McCarthy attacked the US Army as a hotbed of communist activity, the Senate finally censored him and he died a broken politician.
