"What's the Matter with Kansas?" is a book by Thomas Frank that explores the political and cultural shifts in Kansas and the broader American Midwest. It examines how traditionally working-class voters have increasingly supported conservative policies that seem to contradict their economic interests. The book argues that social issues, such as abortion and religion, have taken precedence over economic concerns, leading to a political realignment. Frank suggests that this shift has been driven by a combination of media influence and political strategy, which has reshaped the priorities of voters in the region.
