The availability of rich survey data, and concerns over the ecological fallacy, have led voting researchers to focus on the explanation of individual voting decisions at the expense of accounting for patterns of aggregate election outcomes. This has skewed our understanding of the relative importance of various factors in the electoral process. A framework for analysis of elections at multiple levels is developed and applied using data from twenty-three exit polls from the US Senate elections. Comparable parameters for a simple voting model are estimated for individual voting and for election outcomes. Election-level factors, especially candidates' issue strategies and incumbency, are substantially more important in accounting for election outcomes than in explaining individual voting decisions. Finally, working with election outcomes permits an estimate of a path model of Senate election outcomes that shows key relationships that are not accessible from individual level data.
