Voting without ideology. Evidence from Spain (1979-2008).

Although non-ideological voters make up a considerable share of the electorate, the literature has systematically overlooked their voting behaviour. Using Spanish electoral data from the 1979-2008 electoral period, we seek to identify the alternative cues —in the absence of ideology— these voters may use when casting their ballot. We do not find that evaluations of the incumbent's performance have a greater influence on non-ideological voters, as the retrospective voting literature suggests. Nor do we find that other shortcuts such as candidate evaluations or party identification are used more by this group when they vote. Instead, our results indicate that non-ideological voters have exchanged the traditional ideological shortcut for simple proincumbent voting as a decision rule. [ABSTRACT FROM AUTHOR]
