The plan proposed by Ocasio-Cortez and Markey was a first step, and Bernie Sanders takes it to the next level with his proposal. Some of the reservations that both the labor and environmental movement expressed about the Ocasio-Cortez / Markey proposal are being directly addressed by Sanders. The original Green New Deal proposal didn't preclude the things articulated in the Sanders proposal, what it did was open the door. Now Bernie has opened the door and taken the next step.
