Ahead of the midterm elections, activist and writer Bill McKibben says he has been traveling across the United States with Third Act, the environmental group he founded to harness the power of seniors who care about the climate and democracy. “These elections are also starting to set the groundwork for 2028,” says McKibben, who calls the next U.S. presidential vote “maybe the last election that happens in a timeframe when we still really have an opportunity to affect some of the outcomes of these things.”
