Now he's totally decloaked, publicly a Clinton supporter.

In his book, “Unequal Democracy,” Mr. Bartels shows that “the shift of the Solid South from Democratic to Republican control in the wake of the civil rights movement” explains all — literally all — of the Republican success story.

Now I tend to believe the assertion Mr. Krugman assigns to Mr. Bartels. In context, though, it really sounds like he's implying Obama is undervaluing the impact of the civil rights movement.

Does it matter that Mr. Obama has embraced an incorrect theory about what motivates working-class voters? His campaign certainly hasn’t been based on Mr. Frank’s book, which calls for a renewed focus on economic issues as a way to win back the working class.
