The real keey is to start by attacking the money trail. The local affiliates depend on local advertisers for their existence. Contact all local advertisers and let them know that you will not buy their products or services and that you will organize a boycott of their business. Then contact the local affiliate and let them know what they are doing. Unfortunately, it may have an effect on the local advertisers but if the advertisers contact the station and say that they are pulling ads, it will start a chain reaction. Also, the national advertisers need to be contacted and boycotted.
Additionally, it is time to contact our legislators and demand that CBS release the results of its' internal investigation. They say that they don't want to effect the election. The only way that it would effect the election is if it shows the the Dems were complicit in the crime.
