Don't forget Gary's psychotic wife.
You know...this is the Oscar-winner material for a screenplay? First, you have an idiot who looked good in front of the camera and knew how to fund-raise...so he ran for congress and won. You have his wife...who was a certified nut...refused to go to DC and live there...and lived almost a totally separate life from the husband. You have the immature staff aid who carries on the affair with the congressman. You have the congressman's son who is a liar and likely will face jail time. And there are likely another dozen characters inbetween. With the right actors and Clint Eastwood directing...I've got my Oscar for a screenplay right now.
