One of our favorite sayings here at How to Really Run a City is that there are really three political parties in the U.S.: Democrats, Republicans and Mayors — and only one of them have no choice but to be practical problem solvers. We believe if more politicians acted like mayors, there'd be much less bickering in D.C. Turns out, Bloomberg Philanthropies agrees. For the past six years, the civic-minded global organization has held the Mayors Challenge, a competition that awards cities $1 million prizes to spur innovative solutions to ingrained urban problems. This week, Challenge leader Aparna Ramanan and Challenge grantee, Lafayette, LA Mayor Monique Blanco Boulet, join former Atlanta Mayor Kasim Reed, former Philadelphia Mayor Michael Nutter and Citizen Co-Founder Larry Platt for an eye-opening conversation about what it takes to innovate in a city. (Lafayette's problem might sound familiarly stinky to Philadelphians: old, failing, sewers.) Blanco Boulet believes true innovation must start with a change of mindset. "Critical thinking is just not natural in government. If I don't know where we're having flood issues, I could just choose anywhere [to put the money]. That happens. That's not abnormal for government in the absence of real decision-making." Join us for an episode about cities tackling entrenched problems and the public-private partnerships like Bloomberg Philanthropies that support them. When it comes to facing these intractable issues, as Nutter said, "You have to deal with the consequences of not." Remember to subscribe to the podcast to keep up on all the latest episodes.
