Senator Joseph McCarthy capitalized on the fear of communism during the Cold War to advocate for measures like blacklisting, censorship, and book banning. His actions resonated with a significant portion of the American populace, and at the peak of his influence, almost half of Americans expressed approval for his tactics. This widespread support reflects the climate of fear prevalent during that era.

Even following the Senate's decision to censure him in 1954, McCarthy's support persisted, with Gallup polls indicating that about 40 percent of Americans still backed him. This demonstrates how his political maneuvers were deeply entrenched in the public mindset, highlighting the ease with which democracy can be undermined in times of crisis.
