An opinion poll conducted by Irish Marketing Surveys one month prior to the election in 1997. Interviews were conducted on about 1100 respondents, drawn from 100 sampling areas. Interviews took place at randomly located homes, with respondents selected according to a socioeconomic quota. A range of sociological questions was asked of each respondent, as was their voting preference, if any, for each of the candidates.

In the original version of the data, the ranking matrix contains NAs. Here, NAs are replaced with the number 7, to indicate that all the non-stated preferences are in a tie at the last position (see D'Ambrosio and Heiser, 2016). For details about the data set see Gormley and Murphy, 2008.
