For journalism, it may be the best of times and the worst of times. The national media seems more vibrant than ever. The New York Times, the Washington Post, the Wall Street Journal, as well as the cable news networks are thriving For these outlets the transition to digital was painful, but somewhat successful.

For local news, the story of what happing in your neighborhood, your school board, your city council, is a very different story. Thousands of local newspapers and local radio stations have shut down. The economics of the enterprise has proven to be unsustainable, and even large regional papers in places like L.A., Chicago, and Miami, have proven to be problematic at best and striped by hedge funds at worst.

All of this begs the question of whether our political, cultural, and social divide stems from the top, as is assumed, or whether the hollowing out of the news in our communities, something that should be bringing us together, is at the heart of what’s wrong.

It was the great NY Mayor Fiorello LaGuardia who said that there is no Republican or Democratic way to clean the streets. His comments remind us that locally, there is only the common community interest. Take that away and what’s left is all the bad stuff.
