An interesting piece at the Freakonomics blog looks into the "bigot belt" which is the swath of counties from Texas to West Virginia that actually went more Republican from 2004 to 2008 in the presidential elections. The question, simply put, was whether or not the reason was Obama's race. The answer ended up being yes, but the details of the research offered some enlightening conclusions.
The author, Eric Oliver, looked at whether it was really just race or perhaps the fact that these counties tended to be in heavy coal mining and oil drilling areas had something to do with it. Or maybe it was that these counties had a different racial breakdown than other areas. His conclusion was very interesting: these counties tended to have large white populations in states that were otherwise racially diverse. From the article:
The answer comes in looking at both the county and the state together.
One of the biggest demographic differences between “scarlet” and
“azure” counties is the racial composition of the state population: 72
percent of the “scarlet” counties are in states that are over 10
percent black compared to only 49 percent of the “azure” counties. In a
multivariate regression analysis using all the variables listed above,
the best predictor of a county’s Republican vote margin is its white
racial percentage relative to its state’s black population size. In
other words, the counties where Republican margins grew the largest
tended to be predominantly white places in otherwise racially mixed
states.
These patterns are consistent with research on individual racial
attitudes. Historically, the greatest levels of racial violence
occurred within white enclaves near larger black populations,
particularly when these enclaves are poor and uneducated. Even today,
whites who live in poor, racially segregated neighborhoods within more
diverse metropolitan areas tend to be more racially hostile than whites
who live in either integrated neighborhoods or within largely white
regions. In more diverse settings, locally segregated whites have less
contact with nearby minorities yet also feel greater competition for
jobs and public goods. The combination of both increased racial
competition and racial isolation seems to be a recipe for generating
racial animosity.
As the author concludes we should not be fooled into thinking that this election has somehow catapulted us into an era of racially harmony. The fear of "other" has been with us since we crawled out of the primordial ooze, and I fear it will be ever thus.
