“Brennan and Lomasky point to the expressive function of voting. Fans at a football game cheer not to help the home team win, but to express their loyalty. Similarly, citizens might vote not to help policies win, but to express their patriotism, their compassion, or their devotion to the environment. This is not hair-splitting. One implication is that inefficient policies like tariffs or the minimum wage might win because expressing support for them makes people feel good about themselves.”
