Critics of a popular vote system worry candidates could win by focusing spending and attention on New York, Los Angeles, Chicago, and other dense urban centers, bypassing smaller states almost entirely. Under this concern, a campaign strategy focused on a handful of the largest cities could theoretically secure a national popular vote win while bypassing most of the country's geography. Critics argue this scenario, while contested, illustrates a real structural risk worth weighing seriously. They see the current system as a safeguard against this kind of narrow-geography strategy. Many see this geographic concern as a genuine, not merely theoretical, risk.
