For decades, I have been obsessed with exposing the Clintons and like-minded Democratic politicians’ dangerous foreign policies, challenging liberal naiveté that ignores or excuses such hawkish proclivities, and underscoring the need to withhold support until they embrace more responsible positions. What I am belatedly discovering, as this campaign season is drawing to a close, is that while such concerns are not without merit, such efforts have ended up contributing to what may be an even bigger problem: the anger, frustration, cynicism, self-righteousness, isolation and other self-defeating tendencies on the left. It was such attitudes that played a decisive role in the narrow election victories of Richard Nixon over Hubert Humphrey and of George W. Bush over Al Gore and over John Kerry, resulting in horrific consequences to millions of people in the United States and the world. Indeed, it could possibly even lead this coming week to the most disastrous outcome of all: the election of Donald Trump over Hillary Clinton. It was twelve years ago, at the 2004 Tikkun conference near Washington, DC and in a subsequent edition of the magazine, when I bitterly attacked Democratic nominee John Kerry—in hindsight, the most progressive candidate the party has nominated since George McGovern—in ways that fed such perspectives.
