When Bernie Sanders launched his bid for the Democratic nomination, he was often asked whether he, a democratic socialist, would actually become a Democrat. Now, more than a year after he ignited a movement with his unsuccessful bid, that question is moot. The Democrats have become socialists.
This became official, more or less, Wednesday afternoon, when Sanders rolled out his socialized health-care plan, Medicare for All, and he was supported by 16 of his Senate Democratic colleagues who signed on as co-sponsors, including the party's rising stars and potential presidential candidates in 2020: Elizabeth Warren. Cory Booker. Kamala Harris. Kirsten Gillibrand.
