Every once in a great while, one gets the feeling that Arkansas has turned an important corner. It was that way in 1968, when Gov. Winthrop Rockefeller stood hand in hand with black clergy on the steps of the state Capitol, singing "We Shall Overcome" hours after Martin Luther King Jr. was assassinated, a decade after Gov. Orval Faubus called out the National Guard to block the integration of Central High School. It was that way this month, when the executive director of the Arkansas Economic Development Commission, Grant Tennille, called for Arkansans to accept same-sex marriage, and said that such acceptance would bring great economic benefits to our low-income state. Gov. Mike Beebe didn't say publicly that he agreed with his appointee, but Tennille wouldn't have made the statement without Beebe's consent. Racial equality is much advanced in Arkansas, and one day marital equality will be too. Yet again, government leaders in Little Rock have seen what's coming, and what's right.
