An Odd Thought about the Obama Campaign's Data Collection

On the one hand, there have been many (discussed often on my blogs: 1, 2, 3, 4, 5, 6, 7, and 8) psychological or neurological studies that purported to find supposedly insulting things about us wingnuts. Those studies have generally been marked by small sample sizes and correlations of dubious relevance.

On the other hand, the Obama campaign (presumably run by leftists) was able to turn what would have been a loss in a rational world into a marginal victory by careful analysis of large samples of voters and sticking to data of actual political relevance.

In other words, if there were high-quality data backing up those studies, the statisticians of the Obama campaign have it. They know who high-IQ people vote for. They know who less neurotic people vote for. They know who more impressive people in general vote for. What are the implications of the fact that none of that has been leaked? (I mean, besides the fact that they also have top-notch security people.)
