Democratic socialism is growing in popularity, but what the heck does it even mean?

Sen. Bernie Sanders (I-Vt.) on Monday morning offered this simple explanation in the form of a new video aimed at a U.S. audience:

Among other things, said Sanders, "it means ending the international disgrace of the United States being the only major country on earth not to guarantee healthcare to all people as a right while we end up spending twice as much per capita on healthcare as any other major nation."

Those who support the ideological underpinnings and policy solutions espoused by democratic socialism, concluded Sanders, ultimately "want a government which represents all of us, not just the one percent."
