We review the methodological debate between defenders of the proximity and
directional models. We propose what we believe to be a rigorous and fair te
st of the two models, using the 1997 Canadian Election Study. The analysis
is based on responses to questions in which the various issue positions are
explicitly spelled out. We rely on individual perceptions of party positio
ns because it is individual perceptions that matter in the formation of par
ty preferences but we control for projection effects through a multivariate
model that incorporates, in addition to indicators of distance and directi
on, socio-demographic characteristics, party identification, and leader rat
ings. We also take into account whether a party is perceived to be extreme.
The empirical evidence vindicates the proximity model.
