Sanders Says He’ll Attract a Wave of New Voters. It Hasn’t Happened.

It is the most politically provocative part of Senator Bernie Sanders’s campaign pitch: that his progressive movement will bring millions of nonvoters into the November election, driving record turnout especially among disaffected working-class Americans and young people.

And yet despite a virtual tie in Iowa, a narrow victory in New Hampshire and a big triumph in Nevada, the first three nominating contests reveal a fundamental challenge for Mr. Sanders’s political revolution: He may be winning, but not because of his longstanding pledge to expand the Democratic base. CONT.
