Is the Democratic Party being pulled too far left—or is moderation making a comeback? Jesse Arm, Charles Fain Lehman, and Rafael Mangual discuss the recent government shutdown and the role of the filibuster in shaping legislative outcomes. They analyze tensions in the Democratic Party between radical grassroots movements and centrist pragmatism. And they examine the rise of the “abundance bros” and what this techno-optimist movement says about our current politics.
