The cultural isolation of the elites is primarily driven by the national media

Milwaukee erupts in riots that injure police officers, but it barely becomes national news. Louisiana is devastated by floods, but it takes a week for the national press to notice. The number of fatal overdoses has exploded since 2010. The suicide rate has increased by 2 percent per year since 2006, and hit the highest levels in nearly 30 years last year.

If you view the national news media, based in New York, Washington, Los Angeles and a handful of other cities, as way too monolithic in its political views and driven by conscious and subconscious agendas, the half-hearted-at-best interest in these stories isn’t that hard to explain. These stories aren’t easily used to advance the narrative that Republicans are bad and Democrats are good.

If a terrible natural disaster in Louisiana can be blamed on a Republican president, then it’s one of the biggest stories of the decade. If the lack of a public statement on a Louisiana disaster during a presidential vacation might reflect badly on a Democratic president, it’s best to treat the flood as a “page A4″ story, check-the-box journalism.
