Who's Really on Social Networks: Ideology Edition

Via Business Week, Nielsen-NetRatings provides another incentive for Democrats to embrace social networking as a core component of their youth outreach:

New data from Nielsen//NetRatings show that Republican candidates have a larger constituency on the Internet—36.6% of users 18 and older, compared with 30.8% of users who support Democrats. But the most popular social-networking sites strongly tend toward Democrat and liberal-leaning users. On MySpace, 31.5% of members identify themselves as Democrats, whereas 23.9% say they're Republican. On Facebook, 49.9% of members are Democrats, while just over a quarter, 26%, are Republican.

Yet again, cultural trends provide progressives with a natural advantage over their conservative counterparts.
