In response to a tense post-election moment in the US, the Metropolitics editorial committee has initiated Rapid-Response Peer Review, with a commitment to quickly reviewing and publishing articles that examine organizing and activism around crucial urban issues. Our second call was for papers related to housing policy. John Krinsky argues for a sustained public commitment to housing at the state and local level—a “progressive federalism”—in order to prevent the worsening of New York City’s current housing crisis. Joshua Akers profiles Detroit Eviction Defense, a coalition that has successfully combined a judicial strategy with direct protest. And Elora Raymond deploys unique research on the location of underwater mortgages to suggest that housing, not jobs, may hold the key to reigniting progressive politics in the Rust Belt.
