On the other side of the ledger, history shows that political and social change emanate from persistent pressure—organizing and arguing for a more just world, not settling for what is deemed “realistic” before getting to the negotiating table. Remember when gay rights and gay marriage were “unrealistic”? Remember when voting rights, desegregation, and other basic justice were far from “pragmatic”? They became real through years of dedicated, principled, idealism—by insisting the unrealistic become real.

If liberals and progressives support a $15 per-hour minimum wage, universally accessible health care, fair taxes on corporations and wealth, and meaningful reforms of Wall Street and campaign finance, they should elect a president who actually fights for these things. Sanders has spent his whole political life in pursuit of these ideals, and his campaign has moved these conversations to the fore; Clinton’s record on the other hand shows a consistent pattern of following, not leading on these issues. Clinton’s brand of pragmatism surrenders progressive change to centrism even before negotiations begin.

Change is not, as Clinton has claimed, a matter of “magical” thinking or waving a “wand”—it is about pushing ideas, building movements, and challenging the status quo. Even before the general election, Clinton is campaigning on a deflating and defeatist politics of half-a-loaf “pragmatism,” aiming lower on minimum wage, opposing free college, opposing single-payer health care. With Sanders, there is no question he will push for meaningful progressive change. No candidate can guarantee passage of their platform—but at least Sanders makes change possible.
