Granted, I only occasionally see Fox News coverage during the day, but I've seen very few of these alleged advertisers actually ON Fox News. The only one I noticed was Joseph A. Bank, and they're a regular on other Fox shows.
Most of the rest seem to be gold salesmen, ambulance chasers and other assorted subprime advertisers. Still waiting for Red Wigglers, the Cadillac of Worms to chime in.
