There is zero chance of Clinton achieving that. Though she has shifted her programme to the left rhetorically, her deep roots among the free-market elite and her inability to engage with Sanders young supporters militate against the kind of bandwagon you need to enact generational change.
Sanders has proved inept in handling the black vote in the south. His justification that the south is conservative is a euphemism for the fact that Clinton has plugged into the religious and political patronage system there, and he has not. Instead of excuses, he should be pitching hard to the southern black delegates hes going to need to defeat Clinton at the convention.
But Sanders has something that progressive America needs: the ability to build and sustain a movement. Since 2011, the huge weakness of the progressive activist generation has been their tendency to flip from heroic actions Wisconsin, Occupy, the Black Lives Matter movement to footsolider status in short-lived presidential campaigns.
By contrast, the right has a grassroots movement that, aided by the dollars of the Koch brothers, will harass and sabotage the next Democratic president. It is this movement that has delivered the local counter-revolutions on abortion; that harries migrants; that passes byelaws disenfranchising black voters.
The progressive majority in America needs to become a counter-movement. It needs to occupy not just the occasional park, university or road junction. It needs to occupy the actual political space now squatted by the right: the town hall, the state Capitol, the courtroom, the education board, the voter registration system.
That movement would have to neutralise rightwing working-class opposition by appealing across the formal divide of politics to the desire among many on the right for economic justice. It can only do that by fighting the power and privilege of the very people pouring money into the Clinton campaign. Its hard to imagine Hillary Clinton doing that. A lifetime in elite politics and a bank account enlarged with speaker fees from Goldman Sachs stand in the way. With Bernie Sanders you dont need to imagine.
