Petty political fights distract from the Vermont senator’s goal of a long-lasting movement.
Bernie Sanders’s beliefs have been obvious from the start. He thinks wealthy elites exert too much influence over American politics. He wants the U.S. government to lessen income inequality. He believes climate change is a pressing threat to the world. The clarity and overarching ambition of his agenda has been central to his appeal and expectations-defying political success so far.
If Sanders wants his political revolution to last, he will need to win widespread support for his ideas well into the future. Yet as the primary election draws to a close, the campaign has increasingly made arguments that may undercut the long-term viability of the movement that has coalesced around the Vermont senator.
