Version V2

This data collection, fielded on September 12, 1989, consists of responses to a survey of voters in the New York City Democratic and Republican mayoral primaries. Respondents were asked which mayoral candidate they voted for, how much they liked that candidate, when they decided on that candidate, which issues and factors most affected their vote, how the Bensonhurst incident influenced their vote, if race was a factor in voting, and if they had been contacted by phone on election day about voting. Respondents also evaluated Ed Koch's job performance, expressed favorable/unfavorable opinions of each candidate, speculated on David Dinkins' performance should he be elected mayor, and indicated who they would favor in a runoff between Koch and Dinkins in the general election. Additional items include how respondents voted in the 1988 Democratic presidential primary and in the 1989 primary for municipal offices. Demographic information includes sex, race, age, political orientation, education, family income, union membership, employment, birthplace, housing situation, parental status, subway usage, and sexual orientation.

The election surveys were conducted at polling places among a sample of voters immediately after they cast their votes. The precincts are a random subsample of those used by CBS News for estimating election outcome. Sample precincts were selected with probability proportionate to the total vote cast in a recent past election. The sampling frame consisted of all precincts in New York City. Within precincts, respondents were selected on a systematic random basis.
