This article presents tests of effects of social class background on v
oters' perceptions of most and least favoured federal parties, perceiv
ed party differences and subjective class voting. The data were taken
from the 1984 Canadian National Election Study. The results show that
subjective class voting extended to voters' beliefs about least liked
parties. And the greater the perceived differences between voters' pre
ferred parties and their second and third choice parties, the greater
the level of class voting. An index which combined respondents' percep
tions of the class orientations of most and least liked parties increa
sed the estimate of the level of subjective class voting that takes pl
ace. The results suggest that this index provides an improved way of a
ssessing subjective class voting. This index is a useful improvement u
pon previous measures because it incorporates information on the exten
t to which voters see Canadian politics as presenting class-based alte
rnatives. This is the conceptual domain of the dependent variable in t
he literature on subjective class voting, but perceived class-based al
ternatives are seldom measured directly.
