Why sadly? That makes no sense at all....that's what politicians do after they leave office...they are sought after by business, industry and all others who have a stake in how the congress rules on that which affects their bottom line. This isn't new nor is it something we are going to stop. You can't forbid a politician from making a living at what he knows to do. They all do it.
I will not give Newt a pass because "they all do it". They all stink.
