...With uncomplicated language and simple sincerity, Sanders has rallied millions of Democrats under the banner of “democratic socialism”—a kind of neo–New Deal liberalism, set against Barack Obama and Hillary Clinton’s attempted synthesis of Great Society policies and Third Way politics—and moved “socialist” from the realm of epithet to legitimate label.
Win or lose, that counts. It’s the Democratic analogue to Reagan’s 1976 primary against Gerald Ford—a sign of the times and of the future. If Sanders wins Iowa, New Hampshire, and the nomination, then he’ll bring (or drag) the Democratic Party to the left. If he loses, then he’ll represent the largest faction in the party, with the power to hold a President Hillary Clinton accountable and even shape her administration, from appointments and nominations to regulatory policy.

The Iowa caucus will make or break the Sanders campaign. Without a win, it’s hard to see his path to the nomination. But it means little for his legacy. Sanders is already a historic candidate—the first socialist in a century to build a genuine mass movement in American party politics. And whatever the Democratic Party is in the next 20 or 30 years, it will owe a great deal to Sanders and all the people—young or otherwise—who felt the Bern.
