Heather Cox Richardson (a must-follow) writes in her March 22, 2025, Substack that Senator Smith stood up against the damage McCarthy and his ilk were doing to the nation.
On June 1, 1950, with McCarthy sitting two rows behind her, Smith stood up in the Senate to speak. “Those of us who shout the loudest about Americanism in making character assassinations are all too frequently those who, by our own words and acts, ignore some of the basic principles of Americanism,” she said. Americans have the right to criticize, to hold unpopular beliefs, to protest, and to think for themselves, she said. She condemned those trying to stifle dissent.
“I do not want to see the Republican Party ride to political victory on the Four Horsemen of Calumny—Fear, Ignorance, Bigotry and Smear,” she said. “As an American, I condemn a Republican Fascist just as much as I condemn a Democrat Communist. They are equally dangerous to you and me and to our country. As an American, I want to see our nation recapture the strength and unity it once had when we fought the enemy instead of ourselves.”
Senator Smith ended with a warning: “It is high time that we all stopped being tools and victims of totalitarian techniques—techniques that, if continued here unchecked, will surely end what we have come to cherish as the American way of life.”
This is her full speech; it's worth reading and gaining strength from her words.
