So, the deals McCain worked for the cable and telecomm companies were commonplace? He gave that treatment to everyone? Bring out the investigators! I'd say the boxing and tribal gaming industries would be a good place to start.
I remember reading on “Running John”, Amy Silverman’s web site on John McCain (reporter for Phoenix New Times), that McCain had been involved in some kind quid pro quo with the airlines, as well. This was back in 2000. I used to have all the John McCain articles bookmarked on my old computer, but I deleted them before setting up this one.
