In the summer of 1950, outraged by Joseph McCarthy’s anti-Communist inquisition, Margaret Chase Smith, a Republican senator from Maine, stood to warn her party that its own behavior was threatening the integrity of the American republic.
“I don’t want to see the Republican Party ride to political victory on the four horsemen of calumny — fear, ignorance, bigotry and smear,” she said. “I doubt if the Republican Party could — simply because I don’t believe the American people will uphold any political party that puts political exploitation above national interest. Surely, we Republicans aren’t that desperate for victory.”
