The “Cologne School” of electoral research, which flourished during the 1960s and early 1970s, sprang from research conducted by Erwin K. Scheuch and Rudolf Wildenmann, and included studies carried on by their students. As exemplified by the ten studies reviewed here, it brought to West German political sociologists the theories and findings from American electoral research, tested some of its assumptions with West German data on voting behavior, and expanded and refined its basic notions in a comparative perspective. Especially significant were findings stressing social context as a factor influencing voting, more useful distinctions among kinds of “floating voters,” the lesser importance of party identification in the Federal Republic than in the United States, and the greater importance for West German voters of issues and ideology.
