This brief essay examines emergent spaces for politics and emergent political actors. The particular concern here is with types of politics that do not run through the formal political system, one with shrinking options for a growing number of US citizens and immigrants. Informal political actors and street-level politics in cities are major instances of this. US cities have a long history of street-level politics. The contents, the purposes, the mobilizers and the enactors of these politics have changed over time. Today's global cities are a very specific type of place because they bring together both the most globalized sectors of capital and the new transnational professionals, on the one hand, and a growing number of immigrants and native minoritized groups in a single, complex space.
