Joseph Raymond McCarthy was an American politician infamous for his anti-communist crusade in the 1950s. A few synonymous terms for McCarthy are 'witch hunter' or 'red baiter' due to his tendency to engage in witch hunts against suspected communists, often with little or no evidence. He was also called the 'Senator from Wisconsin' as he represented his state in the United States Senate and was known for fueling the "Red Scare". Some people referred to him as a demagogue as he used fear and paranoia to further his political agenda. In conclusion, Joseph Raymond McCarthy is known for many things, but most infamously as a witch-hunting, red-baiting, fear-mongering politician.
