McCarthyism in America deserves at least one long blog and probably several of them. But to give you a summary of McCarthyism. It was about one U.S. Senator from Wisconsin Joe McCarthy who was anti-communist to the point that he didn’t believe democracy or liberal democracy could survive in the United States with any link to it. Especially inside the United States Government that he had to do everything in his power that he had as a member of Congress to absolutely destroy it.
Senator Joe McCarthy saw his anti-communism as the ticket to bigger and greater things as far as his political career. And perhaps something that would get him to the White House post the Eisenhower Administration. And he took it as far as he could to get everything out of it that he could politically. To the point that he not only destroyed his own political career, but destroyed the professional lives of a lot of good innocent Americans.
