The respondents (voters) were selected through multi-stage stratified random sampling procedure. At the first level, 56 Lok Sabha constituencies in the General, Scheduled Castes(SC) and Scheduled Tribes(ST) categories were randomly drawn, spread across five regions (covering all most all states). At the second level, in each Lok Sabha constituency, two Assembly Constituencies were randomly selected. At the third level, within each Legislative Assembly Constituency, four polling booths were randomly selected. At the fourth level, sample of 30 respondents (voters) whose name appeared in the polling booth list was drawn randomly using a fixed sampling interval within each polling booth.
