Since the days of Franklin D. Roosevelt, the traditional Democratic Party has combined some degree of social moderation — albeit often too timid on issues related to gays and racial minorities — with a unifying message of economic growth, national security and upward mobility. Although business interests sometimes supported them, the old Democrats primarily directed their appeal to urban, and later suburban, middle- and working-class voters.
By the 1970s, many of these voters were headed rightward, as Democrats’ positions on social issues, defense and civil rights moved sharply to the left. Seeking to make up for some of the loss of some traditional FDR voters, Bill Clinton reoriented the party to include the rising class of information workers who were often socially liberal but fiscally conservative. But Clinton’s political genius and down-home image also helped Democrats retain some New Deal working-class support, even while forging stronger ties to tech companies, the rising professional class and Wall Street.
The third faction, the resurgent left, led by Sen. Bernie Sanders of Vermont, grew out of the clear failure of the second Democratic Party, led by its elite wing, to address the consequences of neoliberal economics, notably increased inequality, reduced social mobility and, to some extent, environmental degradation. To these activists, the Clintonian party is not much more than a light version of mainstream Republicanism.
