Tamil Nadu, known for its egalitarian image and Dravidian movement, still heavily relies on caste in elections. Studies show three communities—Vanniyakula Kshatriya, Mukkulathor, and Kongu Vellalar—dominate candidate selections. The DMK-led coalition fielded 45% candidates from these groups; the AIADMK-led front fielded 55%. Both percentages increased from five years prior, indicating growing caste-based candidacy patterns.
