India’s delimitation debate, beyond seat reallocation, profoundly shifts states’ political power, a game theory analysis reveals. Using the Shapley-Shubik Power Index, the study shows southern states face significant power loss (e.g., Tamil Nadu's 22pp drop) while northern states like Uttar Pradesh gain. The Women's Reservation Act is strategically tied to delimitation, making opposition politically costly despite concerns over regional power rewiring. Demographic disparities suggest future delimitation will intensify these shifts. The authors conclude the struggle over regional power will persist, influenced by political realignments.
