Joseph McCarthy

Context: In 1942, shortly after the U.S. entered World War II, McCarthy joined the United States Marine Corps, despite the fact that his judicial office exempted him from military service. His college education qualified him for a direct commission, and he entered the Marines as a first lieutenant.  McCarthy reportedly chose the Marines with the hope that being a veteran of this branch of the military would serve him best in his future political career. According to Morgan, writing in Reds, McCarthy's friend and campaign manager, attorney and judge Urban P. Van Susteren, had applied for active duty in the Army Air Force in early 1942, and advised McCarthy: "Be a hero--join the Marines." When McCarthy seemed hesitant, Van Susteren asked, "You got shit in your blood?"  He served as an intelligence briefing officer for a dive bomber squadron in the Solomon Islands and Bougainville for 30 months (August 1942 - February 1945), and held the rank of captain by the time he resigned his commission in April 1945. He volunteered to fly twelve combat missions as a gunner-observer, acquiring (or perhaps giving himself) the nickname "Tail-Gunner Joe". McCarthy remained in the Marine Corps Reserve after the war, attaining the rank of major.  He later falsely claimed participation in 32 aerial missions in order to qualify for a Distinguished Flying Cross and multiple awards of the Air Medal, which the Marine Corps chain of command decided to approve in 1952 because of his political influence. McCarthy also publicized a letter of commendation which he claimed had been signed by his commanding officer and Admiral Chester W. Nimitz, then Chief of Naval Operations. However, his commander revealed that McCarthy had written this letter himself, probably while preparing award citations and commendation letters as an additional duty, and that he signed his commander's name, after which Nimitz signed it in the process of signing numerous other such letters. A "war wound"--a badly broken leg--that McCarthy made the subject of varying stories involving airplane crashes or anti-aircraft fire had in fact happened aboard ship during a raucous celebration for sailors crossing the equator for the first time. Because of McCarthy's various lies about his military heroism, his "Tail-Gunner Joe" nickname was sarcastically used as a term of mockery by his critics.  McCarthy campaigned for the Republican Senate nomination in Wisconsin while still on active duty in 1944 but was defeated by Alexander Wiley, the incumbent. After he left the Marines in April 1945, five months before the end of the Pacific war in September 1945, McCarthy was reelected unopposed to his circuit court position. He then began a much more systematic campaign for the 1946 Republican Senate primary nomination, with support from Thomas Coleman, the Republican Party's political boss in Wisconsin. In this race, he was challenging three-term senator Robert M. La Follette Jr., founder of the Wisconsin Progressive Party and son of the celebrated Wisconsin governor and senator Robert M. La Follette, Sr. CANNOTANSWER
