DMK leader Stalin's leadership style and policies have inadvertently contributed to the growth of the BJP in Tamil Nadu. His government's decisions, like imposing liquor restrictions, have alienated certain voter segments and created dissatisfaction. The BJP has capitalized on these grievances, positioning itself as an alternative. Additionally, ideological differences between the DMK and BJP have pushed some voters towards the latter, seeking a more conservative agenda. Overall, DMK Stalin's governance has unintentionally provided the BJP with an opening to expand its influence in the state.
