Liberal groups are eyeing a Democratic presidential win in 2020 as their chance to answer the conservative judicial machine. At the American Constitution Society, they’re preparing for that possibility with the selection of former Democratic Sen. Russ Feingold as the group’s newest president.

Feingold recently spoke with The National Law Journal about his vision for ACS, the importance of the rule of law, and how he’ll address diversity within the legal profession and on the bench.
