Some of these trends fit stereotypes: Those who pay attention to sports, either on their desktops or on mobile devices, are more likely to vote Republican. Those who listen to music, look for a job or peruse the personals — think younger, single searchers — are more likely to vote Democratic.

And those most proficient with mobile devices are less likely to vote, because they’re more likely to be younger than those who use computers to navigate online. Take online banking: The average person who uses his or her computer to keep up with their finances is much more likely to vote than someone who checks in on a mobile device, and leans far more Republican.
