7. During the 1950s, Joseph McCarthy wanted to be reelected in 1952, in which he would need a winning issue as he had acquired a reputation for being an ineffective legislator in his first 3 years in the Senate. McCarthy charged that Communists were taking over the government. He accused many people of disloyalty without providing evidence and claimed he had proof of 57, 81, and 205 Communists in the State Department. He also charged that the Democratic Party was guilty of 20 years of treason for allowing Commuynists infiltration into the government. He then made accusations against the US army, which led to an investigation. His bullying of witnesses alienated his audience and costed him public support, and he was condemned for improper conduct that "tended to bring the Senate into dishonor and disrespute".
