evidence: The study, based on a survey of more than 7 lakh respondents across every parliamentary constituency (and which predicted the 2019 results spot on), brings a detailed breakdown of voting preferences across seven key demographic parameters: gender, geography, family income, education, occupation, community/caste and age. [...] For 37 per cent of the respondents, the prime ministerial candidate was the most important factor, while 25 per cent voted on the basis of the local candidate. This reflects the presidential nature of the 2019 poll campaign. Only 3 per cent of the respondents said they voted based on the promises made by the party and its manifesto.
