This paper uses data obtained by a large statewide survey of Massachusetts residents to measure the relative importance of certain motivations in influencing the overall statewide vote on Proposition 2 1/2. Proposition 2 1/2 severely restricts the ability of Massachusetts cities and towns to raise tax revenue for local services. Interviews were conducted by a professional survey firm during the 2 weeks following the vote and were based on a survey instrument written specifically for this purpose. Section I provides an overview of the voting model. Section II reports and interprets the results, and section III summarizes the conclusions. The most important factors leading to increases in the favorable vote were the views toward inefficiency and waste in government. The survey results clearly indicated that the vote for Proposition 2 1/2 was much more of an attempt to obtain lower taxes and efficient government than to reduce the level of public services. Appended are four references and five tables providing data on the impacts of the statewide vote for Proposition 2 1/2 on several different factors: (1) preferred and expected changes in service levels; (2) inefficiency and waste; (3) spending and taxes; (4) tax reform; and (5) relative fiscal status.
