Robo-Calling is illegal in Indiana, which is why the McCain campaign is using call center workers. It looks as if they were expected to read the same script that is used in the robo-calls going out currently. In it, Obama is called "dangerously weak on crime" and hits Obama and his "liberal allies" for having a "disturbing history of coddling criminals."

The interesting thing, among many interesting things about this, is that call center workers generally are paid extremely badly and are under high levels of stress in terms of numbers of calls they are supposed to make in a certain period and so on. It says a lot that these stressed out, vulnerable workers said, "Enough" – complained about the script, and when threatened, made the decision to walk out rather than be part of the slime campaign.
