Kerala polls 2026: From thin margin wins to increasing NOTA, what last elections vote share reveal | India News
As Kerala moves towards the 2026 assembly elections, data from the 2021 polls indicate that electoral contests in the state will remain highly competitive, with narrow victory margins, fragmented vote shares and a small but steady NOTA presence shaping the political landscape.According to an analysis by the Association for Democratic Reforms (ADR) and Kerala Election Watch, NOTA (none of the above) had a vote share of 0.47% in 2021, with 97,695 voters opting for it out of over 2.08 crore votes cast. The number was almost unchanged from 0.5% in 2016, pointing to a consistent but limited protest vote that has yet to influence election results.
At the same time, election-phase data showed that most victories in 2021 were far from decisive. The average vote share of the winning candidates was 47.98%, with only 39 of the 140 MLAs receiving more than 50% of the vote. The majority, 101 winners, were elected with less than half the votes, reflecting the impact of multi-faceted contests involving Left Democratic Front (LDF), United Democratic Front (UDF), NDA candidates and independents.The margin of victory speaks for more competition. Two constituencies were decided by less than 500 votes, while a large number of seats saw margins below 10%. Only five constituencies recorded margins above 30%, making landslide victories rare. Of the re-elected legislators, about 46% won by a margin of less than 10%, suggesting a limited power advantage.The ADR assessment highlights that such sub-50% wins are a structural feature of Kerala’s electoral system rather than the exception. In several constituencies, the runner-up candidates remained within close range, indicating that small changes in vote share could alter the outcome.NOTA usage, though limited, varies across constituencies. Thalassery recorded the highest number of NOTA votes at 2,313, while Kalamassery saw around 0.97% votes going to NOTA. Other constituencies like Chittoor, Manjeri, Sultan Bathery, Vallikunnu, Paravur, Thripunithura and Alappuzha also crossed 1,000 NOTA votes. However, NOTA did not affect the results of any seat.Wider electoral patterns from 2021 add to the complexity. ADR data shows that 77 winning candidates were millionaires, while 99 MLAs declared criminal cases. Only 11 women were elected to the Legislative Assembly. Despite these factors, voters continued to support candidates based on party strength and local dynamics rather than turning to protest votes.Trends after the 2025 local body elections indicate a possible change before 2026. Although the LDF retained nearly 40% vote share, it saw significant seat losses in rural and urban bodies. The UDF polled 43.21%, while the BJP-led NDA maintained around 16%, with gains driven by good seat conversion. In terms of assembly segments, the UDF led in 81 constituencies, compared to 57 for the LDF, with several seats showing narrow margins.In at least 32 seats, the LDF’s margin of defeat was between 1,000 and 10,000 votes, reinforcing the importance of micro-level swings. The data also points to sharp three-cornered competition and weakness in the urban segment.Taken together, the numbers suggest that elections in Kerala are governed less by sweeping mandates and more by closely fought contests. As the state approaches the 2026 elections, even small changes in vote share, including any increase in NOTA from the 0.47% baseline, could be significant in tightly contested constituencies.(with input from agencies)
