Tamil Nadu Politics: Caste Equations Evolve, 2026 A Turning Point?

• Tamil Nadu's electoral politics is still shaped by caste, but in increasingly fluid ways, influenced by regional dominance, welfare, and leadership.
• Key regions like Kongu Nadu (Gounders), Cauvery Delta (DMK stronghold), Northern belt (Vanniyars), and Southern districts (Thevars) have distinct caste compositions.
• Traditional caste vote banks, such as Mukkulathor in the south and Gounders in Kongu belt, are fragmenting due to internal divisions and welfare politics.
• While Dravidian ideology opposes caste hierarchy, practical politics relies on caste arithmetic for candidate selection and mobilization.
• Beyond caste, welfare politics, the 'pink ballot' of women voters, and Gen-Z's focus on leadership and employment are becoming crucial factors.
