The first few contests in the Democratic presidential primary race have been fought in states that are small and somewhat quirky economically. There aren’t many states where voters care as much about ethanol subsidies as they do in Iowa, or where culinary unions wield as much power as in Nevada.
All of that will change on Super Tuesday. The 14 states voting make up nearly 40 percent of the population, and an even larger share of gross domestic product, with all the demographic and economic diversity those numbers suggest. CONT.
