Because logrolling allows special-interest groups a voice in the political process, programs that benefit a minority group can get the approval of a majority. However, this may not be in the best interest of the majority. Special-interest groups typically do not represent the typical voter, but rather, small branches of minority ideologies (Holcombe 2006). Voting results with or without logrolling will differ only if the minority is more interested in an issue than the majority, enough to separate the marginal voters from the majority. Studies show that lobbying and political pressure exerted by special-interest groups are not atypical behavior in a modern democracy (Buchanan and Tullock 1962). Conditions imposed upon the social choice of the legislature imply a more severe restriction on the individual voter's preferences than the theory of logrolling presented by Buchanan and Tullock and presumed by Arrow's General Possibility Theory (Wilson 1969).
