For California Voters - Pass it on...
If you haven't already voted by Absentee ballot, and don't trust the touch-screen voting systems or their lack of paper trail, you have the right to request a paper ballot at your polling place.

For Voters anywhere...
Double-check your ballot carefully. If you make a mistake, or if you even think you made a mistake, call a poll-worker immediately. If you think the voting equipment didn't register your vote properly, call a poll-worker immediately.

I don't care who you don't trust. Do your part to make this a clean election, and by that I mean make sure your vote matches your intent.
