A called "Engage DC" has collected data and run surveys to try and understand the preferences of people on each website. They say that the sites involving commerce are populated by conservatives. For example, Amazon, PayPal, eBay, and Zillow. When it comes to the liberal-minded, they're spending online time at sites such as Quora, BuzzFeed, and Wikipedia. Engage DC describes these sites as having an "emphasize on information and knowledge".

Taken together, Engage DC imagines the presidential campaigns waging a battle for voters. On one side are the (liberals) "Etsy-shopping, Spotify-listening Tumblr readers" and on ther other (conservative) "eBay-shopping, Pandora-listening FarmVille players".
