John Edwards was on the campaign trail yesterday, seeking Black votes in the Tuesday primary in South Carolina, a state he considers to be a "must win" state. In a speech given in a primarily black church, he assailed drug companies for running advertisements for their products. Does he suggest that they should not be permitted to run ads? Does he suggest the same for lawyers who infest the airwaves with their ads? (He made his fortune as a trial lawyer, suing tobacco companies for damages.) Does he support banning political ads as well? Where does he draw the line?
