Sen. Bernie Sanders (I-Vt.) has spent the last year campaigning for the Democratic presidential nomination the only way Bernie Sanders knows how to campaign. Hes run as an unabashedly progressive , issues-driven candidate, determined to make democratic socialism palatable. Hes headlined massive rock-concert-like rallies and promised that record numbers of young voters would turn out to the polls.

The strategy was validated early with a blowout victory in the Nevada caucuses, powered by Latinos of all ages, the demographic group that his campaign had been boasting would be his secret weapon. If Sanders could also energize a larger base of working-class Americans behind him, it likely would be enough for him in a fragmented Democratic field of strong contenders.

Then it fell short.
