Baby Names Reveal Parents' Political Ideology | LiveScience:
"The results revealed that overall, the less educated the parent, the more likely they were to give their child either an uncommon name (meaning fewer than 20 children got the same name that year in California), or a unique name (meaning only one child got that name in 2004 in California). When parents had less than a college education, there were no major ideological differences in naming choice.
However, among college-educated whites, politics made a difference. College-educated moms and dads in the most liberal neighborhoods were twice as likely as college-educated parents in the most conservative neighborhoods to give their kids an uncommon name. Educated conservatives were more likely to favor popular names, which were defined as names in the top 100 in California that year."
