Republicans who live closer to the U.S.-Mexico border are less likely to support constructing a wall than those who live farther away. After a mass shooting, gun sales and permit applications skyrocket in nearby communities. Experiencing an extreme weather event like a hurricane or flood can encourage someone to attribute climate change to human activity. Why do we react so differently to faraway events and ones that take place on our doorsteps, and what does this reveal about our political landscape?Proximity Politics is a groundbreaking examination of the role of distance in shaping attitudes, behaviors, and understandings of the world. Analyzing geocoded survey data, Jeronimo Cortina documents the crucial ways space and place influence public opinion. He demonstrates that the closer someone is to an event, social group, or policy, the likelier they are to have first-hand, specific, grounded knowledge of the subject. Conversely, distance leads to detachment, making it more likely that decontextualized or unreliable information and individual or group biases will prevail. Considering a range of case studies, from virus outbreaks to protests, Cortina unravels how spatial, emotional, temporal, social, and cultural distances affect public opinion. Bringing together quantitative and qualitative data in an accessible style, Proximity Politics shows that even in today’s interconnected world, we are still profoundly influenced by what happens next door.
