Everybody remembers McCarthy but only the democrats remember Richard Nixon and what he did to Alger Hiss. Watergate was payback.
Watergate was payback for exposing a traitor. Hiss was guilty and should have been executed, along with other agents of soviet influence in the government.
Everybody remembers McCarthy because he is still shown as an extremist in every social studies class in America. They are sure to get students to remember him with fear, when in fact he should be a hero, definitely a prophet!
