A deeper dive into Nielsen's data offers revealing demographic data for Obama's and the Republican candidates' sites in January:
Rick Santorum's campaign site got the highest percentage of female voters (60%), while male visitors dominate the pages of Ron Paul (56%) and Newt Gingrich (51%).
Ron Paul, the oldest of the Republican contenders, has drawn plenty of the youngest visitors: more than 30% are less than 34 years old. More than 50% of the eyeballs on Obama's site are older than 50, and people aged 50-64 are the most concentrated age group on his site.
Gingrich's online audience is among the most wealthy and educated -- more than 25% earn at least $100,000 annually, and 50% have at least a four-year degree.
Finally, Mitt Romney's campaign had the highest percentage of Hispanic visitors (17%).
