From BoingBoing:

If you experience any irregularities in voting today, call 1-866-OUR-VOTE, the hotline for the National Campaign for Fair Elections. EFF lawyers and many others are standing by across the country to take legal action to remove malfunctioning voting machines, keep polls open, etc.

I voted this morning using an optical reader and didn’t experience any problems, but did notice a few. A couple people were turned away due to Arizona’s ridiculous photo ID law and precinct changes. Some voters had problems reading the tight print on the optical ballot, but I won’t really blame the machine for that. There was a single DRE at the polling station that seemed unused- I think it was for specific disabilities.
