Chicago mayoral candidate Gery Chico's video, above, is about "trackers" at his events sent by Rahm Emanuel's mayoral campaign. Assigning "trackers" to monitor rival events is now standard for a lot of campaigns--but usually trackers are told to properly identify themselves when asked. In the video, Emanuel trackers clearly do not do that.

UPDATE

Emanuel spokesman Ben LaBolt said in reply to the video, "If attending a public event to see what is said about the campaign is espionage, Tom Clancy is going to be mighty disappointed."
