Tom Nichols: “In a more normal time in American life, people had to leave politics for having a nanogram of Trump’s baggage. Think of the late Senator Thomas Eagleton, the 1972 Democratic vice-presidential pick who had to drop out of the race because he’d been treated for depression. The idea—how old-fashioned it seems now—was that America could not risk any possible mental-health issues not only in the president, but even in the person next in the line of succession.”

“Today, however, we have a former president who exhibits all kinds of signs of a disordered personality—and yet the big worry among many voters (and too much of the media) is whether his opponent is missing a step because he’s roughly 42 months older than Trump.”

“All of this is enervating and exhausting. But that’s the point: Trump is succeeding because he is, to use Steve Bannon’s infamous expression, seeking to ‘flood the zone with shit.’ Trump’s opponents are flummoxed by how he provokes one new outrage on top of another, and each time they believe he’s finally—finally—gone too far. Bombarding the public space with deranged statements and dangerous threats, however, is not a mistake; it’s a strategy.”
