Maths Behind Sri Lanka’s 2024 Election

Key Figures and Critical Thresholds You Need to Know for Sri Lanka's 2024 Election on September 21

by Our Political Affairs Editor

As Sri Lanka gears up for its 2024 presidential election, the stakes are higher than ever. With a total of 17.1 million (171,00,000)registered voters and a high turnout projected at 80%, the race is expected to be intensely competitive. The key figures are striking: candidates will need a minimum of 6,840,100 votes to secure victory in the first round, a daunting target that demands not just solid voter bases but significant new support.

The major players are already making headlines with their strategies to capture the crucial new votes. The SJB, with a strong but insufficient 2,771,980 votes from the last election, faces a Herculean task of adding over 4 million new votes to challenge effectively. Meanwhile, the NPP, starting from a modest 445,958, must rally an additional 6 million voters—a tall order that underscores their uphill struggle. The UNP, led by Ranil Wickremesinghe, finds itself in a particularly precarious position, needing a staggering 6.6 million new votes to overcome its current deficit of just under 250,000.

Adding complexity to the race is the distribution of 1 million new votes. If these are split evenly, the SJB and NPP could each gain an extra 400,000 votes. However, even this boost will not suffice for either party to reach their targets. The SJB would still be short by nearly 3.7 million votes, and the NPP would need to bridge a gap of almost 6 million votes. In contrast, Rajapaksa’s Podujana Peramuna, which secured 6.85 million votes previously, is well-positioned to leverage its existing support and potentially capture the presidency without needing a substantial influx of new votes.

As the election date of September 21 approaches, the political landscape remains fluid, with campaigns intensifying and voter sentiment shifting. The battle for  Sri Lanka’s presidency is set to be a dramatic and high-stakes contest, with each party working tirelessly to sway undecided voters and maximize their appeal. With such high voter expectations and a complex array of variables, the 2024 election promises to be a pivotal moment in Sri Lanka’s political history.
