Civil War Inside Democratic Party
To understand what’s going on now, it might make sense to return to pre-war America, since the Democrats, like the rest of America, are coming to grips with the end of the New Deal era. The party came out of the 1930s having created a new, activist liberal state designed to prevent the return of the great depression by using the government to defend the rights of labour and level the economic playing field that had tilted so steeply toward the wealthy. This liberal state was wildly popular, so popular that Republican Dwight D Eisenhower felt obliged to adopt and expand its premises.
With the country firmly behind what was known as the “liberal consensus”, Democrats continued to expand FDR’s New Deal, recognising that economic fairness required ameliorating racial inequality. When Republicans ran the reactionary Barry Goldwater against President Lyndon Baines Johnson in 1964, the resulting landslide gave Democrats a super-majority in Congress. Working with moderate Republicans to cut racist southern Democrats out of their centrist coalition, they passed the 1964 Civil Rights Act and the 1965 Voting Rights Act, and launched LBJ’s War on Poverty.
But, in part because of the economic prosperity it created, this centre did not hold. In 1968, Republican candidate Richard M Nixon attacked it from the right by bringing white racists into his party, while Democrats destroyed it from the left by shattering over the Vietnam war.
Democrat Jimmy Carter won the presidency in 1976 after Nixon’s spectacular implosion over Watergate, but the party’s crumbling coalition was no match for the rise of Movement Conservatives. Their narrative was simple: the Democrats’ New Deal government redistributed tax dollars from hardworking white men to lazy minorities and women. This easy – and false – explanation for the economic stresses of the 1970s drained working-class Americans away from the Democrats and into the party of Ronald Reagan. And there they stayed, for the most part, even as neoliberalism gutted the American middle class.

There’s a good history summary in this article. Worth reading for that alone.
