The authors use two different data sources to confront the question of
whether a party's primary economic purpose is to sell special favors
or alternatively to provide information and serve as an ideological la
bel. Although not denying the proposition that politicians sell specia
l favors, it does present results consistent with the subordination of
favor specialization to ideological specialization. Besides referring
to earlier published results, this article analyzes individual voting
data in presidential and congressional elections in the United States
and contributions by groups of individuals and types of special inter
est classes to incumbent members of the US Senate and House. These res
ults also imply that there is no need to assume differential abilities
to provide favors to special interest groups to explain differential
success rates in more or less aggregated political jurisdictions.
