I’ve been hearing about these data from Larry Bartel’s book Unequal Democracy for awhile now:
There is a nice op-ed on these data by economist Alan Blinder in the New York Times. The pattern is quite striking: everyone does better under democrats and inequality decreases, slightly. No wonder Republicans try to distract voters by talking about personality and “values”. Anyway, there are lots of potential problems with this kind of analysis, but my understanding is that the book provides a lot more corroborating evidence to support that general case that Republican economic policies have failed and continue to do so today. I’ll have to read it and get back to you.
