The Tamil Nadu Assembly elections 2026 are witnessing a major political escalation driven by controversy, ideological conflict, and the emergence of new political forces.

Alongside this, the election narrative is being defined by the Dravidian model versus Delhi model debate, with the DMK emphasising welfare-driven governance and opposition parties questioning centralisation and political accountability.

This explainer examines the key political developments, campaign strategies, and the broader implications for Tamil Nadu’s political future.
