Bernie Sanders has run a smart and spirited campaign. Even if he eventually loses the Democratic primary, his rise from virtually nowhere to threaten Hillary Clinton from the left offers much-needed optimism in a time of dismal inequality. His invective against Wall Street is accurate and often courageous. He is the rare candidate who doesn’t traffic in patriotic or religious platitudes. But I won’t be voting for him. Sanders has long supported Israeli colonization, including the worst elements of its military occupation.
