Over the past decade, political scientists have with increasing freque
ncy demonstrated that emotions strongly influence mass political behav
ior. One shortcoming of this research has been the failure to distingu
ish between fundamentally different sources of emotional response. In
this article, I draw on theories of emotional response developed in so
cial psychology to argue that emotional reactions to presidential cand
idates are partly rooted in what people know about the political world
(cognitively mediated emotion) and partly independent of political co
gnition (gut-level emotion). Using data from the 1984 and 1988 Nationa
l Election Studies, I develop instruments of gut-level positivity and
negativity and show that these factors strongly influence the presiden
tial vote.
