If McKibben wants RCV to be an issue in the 2020 presidential election, he should support the Green Party. As a climate activist, he should support the Green Party because we are the only option on the ballot for a full-strength Green New Deal to zero out carbon emissions with 100% clean energy by 2030. RCV is not anywhere on Joe Biden’s agenda. Biden’s “all-of-the-above” energy policy is what McKibben has devoted his life to opposing. If we don’t vote for what we want, how are we ever going to get it?
