One reason for the long lines was that almost 10 percent of Georgia’s polling sites had closed over the preceding seven years, despite an influx of about 2 million voters. In a paper due to be published this summer in the journal SIAM Review, Mason Porter, a mathematician at the University of California, Los Angeles, and his students used tools from topology to do just that. Hickok said these techniques are useful not only for understanding the distribution of polling places but also for studying who has better access to hospitals, grocery stores, and parks.
