MICHAEL BARONE on the Doha Round’s collapse: “Farming interests, although only a small part of the economy, have effectively killed a trade agreement that would have been beneficial to many more people. The persistence of farm subsidies in this country, and the much larger farm subsidies in Europe, are an example of how interests of the past have more political clout than interests of the present and future. . . . You can see this in one of the worst policy mistakes of the Bush presidency — the 2002 farm bill.”
