In this AlterNet article, Kevin Griffis travels around the South, trying to figure out why poor whites vote for Bush, even though it is clearly against their own interests to do so. I particularly liked this quote:

Like much of the rural South, each town I visited was relatively poor, overwhelmingly white and voted for President Bush in 2000. At each stop, I looked for working poor and middle-income people, asked them how they voted and why. The answers were depressingly facile, filled with the perfectly parroted lingo of the right-wing echo chamber, and yet, once I dug, often so thin, disconnected and confused that I wondered whether a strong wind (or populist candidate with the right message) might reorder the political landscape.
