Who among these Republicans has the courage to call it what it is?

There’s precedent for the courageous path, should anyone choose to take it. On Feb. 9, 1950, Joe McCarthy gave his famous speech in Wheeling, West Virginia, charging that communists were working in the State Department. The months that followed were very much like these last five months of the Trump ascendancy, as the official party stood mute in the face of the hysteria created by one of its number.

Then in June, one Republican senator said “enough.” Margaret Chase Smith of Maine was a freshman senator, having taken her husband’s seat. She took to the Senate floor and gave a 15-minute speech (PDF), which has gone down in history as her “Declaration of Conscience,” that all of us, starting with leading Republicans ought to be reading this week. Two choice excerpts:

“As a Republican, I say to my colleagues on this side of the aisle that the Republican Party faces a challenge today that is not unlike the challenge which it faced back in Lincoln’s day. The Republican Party so successfully met that challenge that it emerged from the Civil War as the champion of a united nation—in addition to being a party which unrelentingly fought loose spending and loose programs.”

“The Democratic administration has greatly lost the confidence of the American people… Yet to displace it with a Republican regime embracing a philosophy that lacks political integrity or intellectual honesty would prove equally disastrous to the nation. The nation sorely needs a Republican victory. But I do not want to see the Republican Party ride to political victory on the Four Horsemen of Calumny—Fear, Ignorance, Bigotry, and Smear.”

Six of her Republican colleagues signed with her a statement of principles that began: “We are Republicans. But we are Americans first.” So that’s what people can do in the face of extremism, if they want to.
