Studying politics and elections generally is considered the realm of political scientists, but other fields—such as psychology, computational science, and data science—play an important role in understanding how elections work, what influences voters, and who is likely to win an election. This volume offers readers an inside look at how data and technology impact elections and help inform how candidates and their teams run campaigns. It also explores what is and is not known about the psychological aspects of voting and how this can be used for political forecasting, along with the limitations to predicting the outcomes of elections.
