For the first time, working-class whites make up less than half of Ohio's eligible voters, part of a demographic shift in a key Midwestern swing state that is pushing political parties to widen their appeal beyond the once-dominant bloc. Nationwide, working-class whites are more likely to be socially conservative, less optimistic about their futures and skeptical of big government. But in Ohio, the group has been much more politically divided: encompassing deeply religious, GOP-leaning conservatives in rural areas as well as unionized blue-collar Democrats in cities.
