Voting by phone has been ready for 21 years for the other 150 million or so registered US voters. And, if you're off traveling at election time and don't have your laptop, modem, and access, you can pick up any phone in the world and vote.
Not having a graphical interface with the phone is no problem. A paper "ballot worksheet", mailed to voters or published in the news, and a pencil help you prepare your votes so they can be quickly entered by phone. This was successfully demonstrated both in the 1974 Televote trials and in the State of New Mexico's 1992 Mock Election, successfully conducted by telephone.
