Even if internet voting were available, saving the screen is meaningless. Since electronic voting allows the voter to change his/her vote until the election closes, one could save the "politically correct" screen for posterity and bragging rights, then go back and change the vote.
That's s similar tactic used in years gone by for agents to get people into First Class for free. They would enter the info, and print out the roster for the flight attendants. Once the hard copy was printed, they would undo the upgrade in the computer. I don't think it's possible anymore.
