The constitutional frameworks of the 18th century initially granted the vote to a tiny slice — property-owning white men. Over the next 150 years, eligibility widened in staggered pushes: working-class men, non-white men, women, colonized peoples, and finally — in the U.S. — Black Southerners whose constitutional voting rights had been nullified for a century. The mechanism became 'one person, one vote, counted honestly.' Polling, mass media, and party systems all emerged to service that mechanism. By 1990 it was the default worldwide claim, even where the reality fell short.
