When will Republicans reject fear, ignorance, bigotry and smear?

Republican Sen. Margaret Chase Smith of Maine initially thought her GOP colleague Sen. Joe McCarthy might be onto something with his crusade to root out subversives in the State Department. After all, post-World War II, concern was high on issues of national security. But when she examined his questionable “evidence,” Smith instead worried that his bully-boy act would be the true subversion of American values.

Though her June 1950 “Declaration of Conscience,” delivered on the Senate floor and supported by six other Republican senators, never mentioned McCarthy by name, it was clear Smith meant the Wisconsin senator when she said: “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.”

And though Smith certainly wanted Republicans to win, she said, “I don’t want to see the Republican Party ride to political victory on the four horsemen of calumny — fear, ignorance, bigotry and smear.”

While Democratic President Harry S. Truman praised her words, retaliation was swift from McCarthy, who dismissed the effort from “Snow White and the Six Dwarfs” — proving inane name-calling did not originate with Donald Trump.

Smith was removed as a member of the Permanent Subcommittee on Investigations, replaced by an ambitious senator from California, Richard M. Nixon. But four years later, she got to cast a vote for McCarthy’s censure after the beginning of his end, the moment U.S. Army lawyer Joseph Welch asked, “Have you no sense of decency, sir, at long last?”

Cut to today, and the opportunity for members of today’s GOP to take a stand.
