In industrial societies, class, ethnicity, and religion are determinin
g factors in election results. It is believed and local party organiza
tions have been playing ever more marginal roles in national elections
. Has the mass media ended up reducing local parties to mere spectator
s? Are local party machines too weak to lend their support to presiden
tial candidates? This article analyzes the effects that local organiza
tions had on Brazil's 1989 presidential races. Brazil is a kind of cas
e study in the collapse of local party organizations given its interru
ption in political competition, the absence of parties boasting partic
ipation in the country's earlier democratic experience, and the fragil
ity of citizen-party identification. Most observers of the 1989 presid
ential contest effectively affirm that television ''made'' the winning
candidate and that political parties had little or no importance in t
he final results. Nevertheless, the candidates themselves acted as if
party support were relevant and, within the context of Brazilian polit
ics, it was rational for mayors to barter votes in exchange for future
advantages for their municipalities. Throughout the article, the auth
or made use of models of growing complexity in analyzing the voting da
ta on major candidates. These models, which include both measurements
of party inclination as well as socioeconomic and demographic factors,
reveal that candidates attained better results in municipalities wher
e the mayor represented their supporting party. The models underscore
the effects that spatial factors such as ''friends and neighbors'' hav
e on the tactics of local politicians, and also make it possible to di
stinguish between popular and charismatic components and purely organi
zational factors of political support.
