National: The Income Gap at the Polls | Politico
In 1986, the economist John Kenneth Galbraith declared, “If everybody in this country voted, the Democrats would be in for the next 100 years.” But for decades, the consensus among scholars and journalists has been the opposite. In their seminal 1980 study on the question, using data from 1972, political scientists Raymond Wolfinger and Steven Rosenstone argued that “voters are virtually a carbon copy of the citizen population.” In 1999, Wolfinger and his colleague Benjamin Highton again came to the same conclusion: “Outcomes would not change if everyone voted.” Their argument rested upon the fact that polling data did not show large differences in opinions on most issues between those who voted and those who did not. However, a growing literature both within the United States and internationally suggests that, in fact, policy would change rather dramatically if everyone voted. Does this mean that Galbraith was right all along? Not exactly. The reason for the recent shift in the findings is not that the early studies were wrong, but that the preferences of voters and nonvoters are becoming increasingly divergent.
