JOEL KOTKIN: Democrats Could Face an Internal Civil War as Gentry and Populist Factions Square Off:

Broadly speaking, there is a long-standing conflict inside the Democratic Party between gentry liberals and populists. This division is not the same as in the 1960s, when the major conflicts revolved around culture and race as well as on foreign policy. Today the emerging fault-lines follow mostly regional, geographical and, most importantly, class differences.

Gentry liberals cluster largely in cities, wealthy suburbs and college towns. They include disproportionately those with graduate educations and people living on the coasts. Populists tend to be located more in middle- and working-class suburbs, the Great Plains and industrial Midwest. They include a wider spectrum of Americans, including many whose political views are somewhat changeable and less subject to ideological rigor. . . .

Although peace now reigns between the Clintons and the new president, the broader gentry-populist split seems certain to fester at both the congressional and local levels – and President Obama will be hard-pressed to negotiate this divide. Gentry liberals are very “progressive” when it comes to issues such as affirmative action, gay rights, the environment and energy policy, but are not generally well disposed to protectionism or auto-industry bailouts, which appeal to populists. Populists, meanwhile, hated the initial bailout of Wall Street – despite its endorsement by Mr. Obama and the congressional leadership.

Geography is clearly a determining factor here. Standout antifinancial bailout senators included Sens. Byron Dorgan of North Dakota, Tim Johnson of South Dakota, and Jon Tester of Montana. On the House side, the antibailout faction came largely from places like the Great Plains and Appalachia, as well as from the suburbs and exurbs, including places like Arizona and interior California.

Hmm. Map this to the “tea party” protests. (Via NewsAlert).
