In the comments of the last post, The Cold Equations raises a good point that region should be controlled in a model of how whites vote. Here are the results with region added to the model (all the regions are being compared with New England, chosen as the reference group because it is a particularly blue region):
Logistic regression coefficients
Scots Irish .17
Town size -.01
East North Central .61*
West North Central .35
South Atlantic .95*
East South Central .84*
West South Central .1.28*
Even after adjusting for region (and income and population size), Americans of English/Welsh, Dutch, and German descent are significantly more likely to vote Republican, compared to other whites. Implicit ethnicity at work?
