In both tables, all variables with loadings (i.e., correlations) of .60 or more with a factor are in boldface. In the right-hand table, I've deleted all loading lower than .30 to clarify the structure.
The shaded matrix shows that the first six issues all correlate above .60 with the principal component of the original correlation matrix. However, four issues correlate above .60 with the next factor, which is unrelated to the first. These findings disconfirm unidimensionality in the parties' issue positions.
Rotation of the factor matrix, furthermore, shows that eleven of the thirteen issues breakdown into three disctinct clusters of variables, which I have named Economic Leftism, Cold Warism, and Liberalism. One variable relates about equally to all three factors, while another variable stands largely alone.
