Chris Wilson grouped political donations by name:
The data show that names are a strong predictor of support for one party or the other. Looking at names that occurred at least 1,000 times on the donor rolls, it is immediately evident that women give in much greater numbers to the Obama campaign, a fact that the site OpenSecrets.org has also observed. Within a gender, however, some names have much stronger correlations than others. While people with very common names—James, David, Michael—are roughly evenly split between the two parties, names like Brent, Tyler and Clayton are considerably skewed toward the Republicans.
