Democrats are from Tumblr; Republicans are from Pinterest. That is not, perhaps, the most salient takeaway from a survey of young adults released today by Harvard’s Institute of Politics — but it’s certainly the most interesting! (From our perspective, anyway.)

The survey polled 3,058 young Americans in the politically clutch age range of 18 to 29. It asked them, among other things, on which social media platforms they have an account.

For platforms like Facebook, Snapchat and Foursquare, the split between Democrats and Republicans was pretty much even. But several platforms also gave off a distinctly partisan vibe: 52 percent of young Democrats say they’re on Google+, for instance, versus 36 percent of Republicans. (The big news here, of course, is that anyone uses Google+ at all.) Twitter, Instagram and Tumblr all lean to the left. Meanwhile, Pinterest trends heavily Republican — which should come as no great shock.

This would all seem to be good news for Democrats, who rule just about every major social platform. But Harvard’s full survey actually finds that the opposite is true: Although young Democrats may be more active on social media, they’re less active at the polls. #wompwomp.
