The Bradley Effect is defined in Wikipedia as "...a frequently observed discrepancy between voter opinion polls and election outcomes in American political campaigns when a white candidate and a non-white candidate run against each other."
The Effect does not discriminate by political party nor by region. It hapens in the south and it happens in the north. See: http://www.thenation.com/blogs/campaignmatters?pid=268328 >From what I could tell from the above linked-to article, the Bradley Effect ranges from about 9% to 16%. So when Bongo Brazil gleefully posts the results of an opinion poll showing Barack ahead by 6 points I wonder if that translates into a 4 point deficit for Obama once the Bradley Effect is factored in. Also: if you have an election that is MORE important -- such as this presidential election -- does the Bradley Effect become stronger? Or Weaker? I also wonder if the Effect gets stronger when a larger percentage of the electorate are accused of being racist. This is a phenomenon that has been experienced by some on this forum: oppose Barack and risk being called a racist. How will such accused and labelled persons respond once in the privacy of the voting booth? I suspect that they will NOT cast votes for Barack just to spite their accusers, don't you think?
