This is a bit long, but worth reading. I think that the analysis of the rightward turn is mostly correct. I have no doubt that racial divides are a major major part of it. IMHO, it's always been that way. As the old definition of racism put it, "Racism is rich white men laughing all the way to the bank." The economic disasters of the 21st century, the disastrous foreign policy of the first decade of this century, the easy illogical leap from love of country[-as-it-used-to-be] to hatred of country[as-it-now-is], the rhetorical exploitation of resentment--all of that is here, and more.
