By "win back" you clearly refer to the Dem Party, but after Bill Clinton betrayed "his" voter base, and that was followed by Obama doing the same and HRC being her unlikeable and corrupt self the independent, progressive "Dem", Sanders, American values base has been screwed time and time againg by the Democratic Party corporate/big-money establishment, always moving further to the right. Now after the trump "win" (or HRC-establishment-neoliberal loss) the party still is firm;y in the same hands as before! No change we can believe-in, no new Sanders leadership of direction - no meaningful reform! The Schumer, Pelosi, Booker, Cuomo sellout "compromisers still make the rules and hold the power. Look, "compromise" is essential in politics, but collusion and capitulation are NOT!
YES - "We need to continue the Sanders attack on the neoliberal order by offering a compelling vision for social and economic justice."
We need to trumpet the Sanders message of big-money/banker/wall street usury and greed-driven domination and subversion of our broken politics!
No foundational and leadership/'candidate change/reform in the Dem Party, No "winning-back" anyone! Screw me once, shame on you, screw me countless times, shame on me!
