The book does a much better job with its history in the beginning than the culmination of the book. The author begins tracking the history of American electoral politics and takes chapters to also view the history through a slightly different lense, like through race, women, and gerrymandering, that gives a pretty decent picture of the structure of electoral politics. However, by the end it culminates in him chalking up the reason that republicans predominantly support Trump is because of the racis- oh I mean “racial resentment”. He explains the metric of how they came to that and all the questions are essentially a catch 22. Essentially, if you agree with affirmative action, or think that African Americans need to be treated differently than any other minority, then that must mean you have “racial resentment” as opposed to having a different opinion. It seems if that assertion is going to be made he probably should have spent at least a bit of time assessing the polls correlation to his premise. It does some work pinning down how much that is a factor in determining favorability toward a a particular party, but he even asserts that racism is now some covert thing being done and that there are new metrics to judge if someone is racis- sorry I mean full of “racial resentment”. Still not bad, it’s relatively short.
