Yes, voting over the internet is actually happening -- kinda. West Virginia is limiting online voting to citizens living overseas and to people in the military, along with those in the Merchant Marine. The effort is made possible by the US government's Uniformed and Overseas Citizens Absentee Voting Act (UOCAVA), which allows eligible voters to cast ballots via any form of electronic transmission, including fax or email.

That means West Virginia will be the first state to offer online voting by smartphone app.
