Counting for five state assembly elections begins tomorrow, with West Bengal and Tamil Nadu drawing the most attention from political parties, investors, and analysts watching India's electoral calendar ahead of 2029.

West Bengal and Tamil Nadu carry outsized weight in this cycle for different reasons. Bengal is a direct contest between the ruling Trinamool Congress and the BJP, which has been trying to expand its footprint in the state since its strong showing in the 2021 assembly election. Tamil Nadu tests whether the DMK government under M.K. Stalin can consolidate its mandate at a time when the AIADMK and BJP are both seeking relevance in the south.

Why These Two States Matter Most

Together, West Bengal and Tamil Nadu send a significant number of MPs to the Lok Sabha, making their political direction a reliable signal for 2029 general election strategy. A strong performance by the BJP in Bengal would validate its plan to build a southern and eastern base beyond its Hindi-belt strongholds. A decisive DMK win in Tamil Nadu would reinforce the opposition INDIA bloc's argument that regional parties can hold ground against BJP nationally.

High voter turnout in both states has been reported during polling, which typically benefits incumbents when their ground organisation is strong, but can also signal anti-incumbency in contested urban areas.

What to Watch in the Results

The margin of victory in Bengal's urban constituencies and the vote-share shift between AIADMK and BJP in Tamil Nadu are the two numbers most worth tracking. A split in the anti-TMC vote in Bengal could hand Mamata Banerjee a comfortable majority even with modest swings. In Tamil Nadu, whether the BJP manages to win any seats independently would mark a meaningful shift in its southern strategy.

The other three states in this verdict will also shape the overall narrative around which alliance has momentum heading into 2029. Results are expected to come through across the day tomorrow, with clear trends likely by midday.
