If you see something weird or discomfiting or arguably illegal going on at your polling place tomorrow. don't post about it here. Or, at least, don't post first.
You've got two choices tomorrow as to where to phone in your information, and I'm going to advocate doing both. First off, there's Obama Voter Protection:
Call 1-877-US-4-OBAMA (1-877-874-6226) and let them know what problems you're seeing. If you can't get through, use this online form and/or call your local campaign HQ.
Alternately, or in addition, I strongly encourage you to call Election Protection, a nonpartisan organization:
We all love being able to break news here about what we're seeing, but what matters most tomorrow is giving that information to people who can do something about it . And then ... wait, what are you doing at a computer in the first place on Election Day? Get out there. Do More Than Vote.
Lawyers like me will be at polling places all over the country tomorrow to protect every citizen's right to vote in an atmosphere free of intimidation, coercion and deception. But we can't do anything if we don't know what the problem is. So don't post it here -- call it in.
