I think this can be viewed in a bad way when you consider the entities behind it. 1st PBS is heavily Obama and want him to win simply for the historical aspect of him winning. 2nd you have voter registration experts... ACORN. 3rd you have election reform activists who are actually now acting as a wall between a person and voting non-Obama. Activism positions in rescent years has meant support Democrats. Such as the Sheriff who is going to act as a wall to voters by telling them about the lies the most honest politician in Washington has told them about Obama.
