Yeah, I know the outline of the argument. Democratic economic policy would actually lead to a better quality of life, but Republicans use social wedge issues and anti-government rhetoric to keep mostly Christian, mostly white voters on their side.
What I'm asking is whether I could get a lot more depth from reading the book, or if this is a case where you can pick up the argument through secondhand sources.
If it's just a list of all the different things the GOP's campaigned on over the last few decades, I already know the drill. If he gets into the nitty-gritty of demographics or history, that might be different.
For example, I've read an argument that the US has always seen people vote based on their cultural identity, and that the New Deal era of putting economic interests first was an anomaly that only happened because of the Great Depression. I don't know near enough history to lean one way or the other about it.
