CHAMPAIGN, Ill. — "One person, one vote" is often the rallying cry for democratic reform, suggesting everyone should get an equal say in their government.
Yet in some of the oldest and largest democracies, some votes are worth far more than others by design. A Wyoming voter, for instance, is significantly over-represented compared with a California voter. Each state has two U.S. senators, but California has 66 times more people.
