a startling 2012 study by sociologist Arthur O’Connor that showed that residents of red states suffer higher rates of industrial pollution than do residents of blue states. Voters in the twenty-two states that voted Republican in the five presidential elections between 1992 and 2008—and who generally call for less government regulation of business—lived in more polluted environments. Residents in the twenty-two Democratic states that generally favor stricter regulation, he found, live in cleaner environments.
