I urge you and your friends/family to all download VoteStand, the first VoterFraud reporting app. Many groups, such as True the Vote, will be monitoring. And, if you have the application, you can monitor too (as well as report)!
Also: If you see fraud IN the polling place, please go OUTSIDE to report it - it is illegal, in most states, to use cell phones and/or cameras within a polling place.
