"By winning white working-class voters and making inroads with minority voters, Sanders is moving beyond an elite and generational candidate, and forcing Clinton to address reform in a much bolder way, says Greenberg, who was the Clintons’ pollster in their first bid for the White House in 1992. Clinton says she’s a progressive who gets things done, and that she won’t make promises she can’t keep, a message while admirable is not inspirational. "This is not a practical election, this is a change election," says Greenberg. And so far it is Sanders who has capitalized on the hunger for change, while Clinton has relied on her long history of championing liberal causes to resonate with voters, many too young to appreciate what she fought for. Sanders began the way Gene McCarthy did in ’68 with support that was educated and young, and with a focus on the economy, the issue that matters most to these voters. The coming weeks will tell us whether Clinton can revamp her message to meet the moment, and whether she can continue to win minority voters with the same spirit of hopefulness that Robert Kennedy’s too short candidacy symbolized. Otherwise, she risks that mantle being grabbed by Sanders."
