9.4 Divided government and partisan polarization  (Page 6/27)

But over the past several decades, voters have started identifying more with national-level party politics, and they began to demand their elected representatives become more attentive to national party positions. As a result, they have become more likely to pick parties that consistently represent national ideals, are more consistent in their candidate selection, and are more willing to elect office-holders likely to follow their party’s national agenda. One example of the way social change led to party sorting revolves around race.

The Democratic Party returned to national power in the 1930s largely as the result of a coalition among low socio-economic status voters in northern and midwestern cities. These new Democratic voters were religiously and ethnically more diverse than the mostly white, mostly Protestant voters who supported Republicans. But the southern United States (often called the “Solid South”) had been largely dominated by Democratic politicians since the Civil War. These politicians agreed with other Democrats on most issues, but they were more evangelical in their religious beliefs and less tolerant on racial matters. The federal nature of the United States meant that Democrats in other parts of the country were free to seek alliances with minorities in their states. But in the South, African Americans were still largely disenfranchised well after Franklin Roosevelt had brought other groups into the Democratic tent.

The Democratic alliance worked relatively well through the 1930s and 1940s when post-Depression politics revolved around supporting farmers and helping the unemployed. But in the late 1950s and early 1960s, social issues became increasingly prominent in national politics. Southern Democrats, who had supported giving the federal government authority for economic redistribution, began to resist calls for those powers to be used to restructure society. Many of these Democrats broke away from the party only to find a home among Republicans, who were willing to help promote smaller national government and greater states’ rights.

At the same time social issues were turning the Solid South towards the Republican Party, they were having the opposite effect in the North and West. Moderate Republicans, who had been champions of racial equality since the time of Lincoln, worked with Democrats to achieve social reform. These Republicans found it increasing difficult to remain in their party as it began to adjust to the growing power of the small government–states’ rights movement. A good example was Senator Arlen Specter, a moderate Republican who represented Pennsylvania and ultimately switched to become a Democrat before the end of his political career.
