review of a lib book that covers research on racism https://academic.oup.com/sf/article/99/2/e1/5877695?login=true
The book is essentially four distinct studies, tied together by the overarching concern with how much race defines winners and losers in American politics. Chapters 1, 2, and 3 describe the first study, showing that there are stark differences in the political preferences of white voters when compared to every other major racial group and that candidates preferred by Black voters win their elections the least often, at every level from local races to the Presidency. In the second study, reported in Chapter 4, we learn that Black Americans’ policy preferences—what they tell survey researchers they want the government to do in terms of spending—are also less frequently satisfied than those of any other group, though no group’s preferences win out consistently. In both these studies, Hajnal demonstrates that the win-lose gap between Black and white people is larger than the same gap between class groups, genders, ages, or religions—that race is the strongest dividing line in American politics
Pretty sure as a group “left” peoples candidates win even less often.
