Hannity like so many others has fallen victim to the Washington Insider Syndrome. It is incurable.
After hobnobing with these people for years you start to become one of them. It’s part of a big club, and loyalty to the fellow members starts to take precedence in your life.
The US Senate is probably the best example of this. After a few years there you can kiss your principles and beliefs good bye. It’s your relationship with the fellow clubmembers that counts most. Think Trent Lott, Lindsey Graham, Chuck Hagel, Arlen Specter, John Warner.
Ironically, Democrats seem immune to this disease. They remain rigid in their liberal beliefs.
