Conservative poll observers are gearing up for Election Day, when they will watch for possible instances of voter fraud and challenge voters they find suspicious. As ThinkProgress reported, many of these volunteers have been fed false or misleading information about voting rights by the Romney campaign and independent Tea Party groups like True the Vote. True the Vote encourages its poll watchers to “build relationships with election administrators” because “they control the access to the vote.”
