Sept. 10 — The mayors are coming. In recent months, City Hall occupants in Tallahassee, Nashville, and Tuscaloosa have won Democratic primaries for their state’s gubernatorial races. Mayor Eric Garcetti of Los Angeles, former New Orleans Mayor Mitch Landrieu, and former San Antonio Mayor Julian Castro are rumored to be considering White House bids in 2020. City leaders seeking higher office are banking on the idea that voters will respond to what cities embody today: innovation, diversity, and progress.
