Hillary Rodham Clinton has more than earned, through her service to the country as first lady, as a senator from New York, and as secretary of state, the right to be taken seriously as a White House contender. She has flaws (some legitimately troubling, some exaggerated by her opponents), but she is among the most prepared candidates ever to seek the presidency. We are confident that she understands the role of the United States in the world; we have no doubt that she will apply herself assiduously to the problems confronting this country; and she has demonstrated an aptitude for analysis and hard work.
Donald Trump, on the other hand, has no record of public service and no qualifications for public office. His affect is that of an infomercial huckster; he traffics in conspiracy theories and racist invective; he is appallingly sexist; he is erratic, secretive, and xenophobic; he expresses admiration for authoritarian rulers, and evinces authoritarian tendencies himself. He is easily goaded, a poor quality for someone seeking control of America’s nuclear arsenal. He is an enemy of fact-based discourse; he is ignorant of, and indifferent to, the Constitution; he appears not to read.
This judgment is not limited to the editors of The Atlantic. A large number—in fact, a number unparalleled since Goldwater’s 1964 campaign—of prominent policy makers and officeholders from the candidate’s own party have publicly renounced him.
