How Decades Of Democratic Rule Ruined Some Of Our Finest Cities

Urban Blight: A few days ago, filmmaker Michael Moore tweeted, “Flint has voted for Dems for 84 straight yrs” and wanted to know, “What did it get us?” He’s actually on to something.

Don’t drink the water in Flint, Mich. Federal and state officials botched a water supply switch there and ended up contaminating the city’s drinking water with lead. It’s a sad and infuriating story that has gone on far too long. It’s not quite a humanitarian crisis -- blessedly, we don’t see many of those in this country -- but it is a mess.


Of course blame has been liberally tossed around. Republican Gov. Rick Snyder has been sued. Moore wants him arrested. (Obviously there's a limit to Moore's ability to think clearly, and he reached it with his Flint tweet.) Some are convinced that the private sector is the villain, because, after all, isn’t it always? The loopy left even says that the Koch brothers are at fault.

But let’s backtrack to Moore’s tweet. Flint is indeed a Democratic Party bastion. Don’t its decades of Democratic dominance deserve some of the blame? It’s the city’s "Democratic rulers," Reason magazine’s Robby Soave reminds us, who have "robbed city residents blind to pad the pockets of public sector unions." They’ve also been in charge as Flint has become one the country’s poorest cities (the second poorest, says the Census Bureau, for a city of its size), and a haven for criminals -- it’s the most dangerous city in America, according to Business Insider.

I think it's wise to learn from past examples.
