It has been my experience that, once they get in office, elected officials become politicians, which means that their main goal is to stay in office (or move higher up). They love the perks of being an elected official, especially the feeling of importance, and revise their priorities to focus on and cater to the folks they can use to re-elect them. The first thing they do is to consolidate their strength, replacing effective, free-thinking government employees with individuals who will do what is asked without question. What this accomplishes is to scare the rest of the employees into keepiing silent and do whatever it takes to keep their jobs. I find the threat of losing your income transforms moral and ethical people into meek little well-behaved robots.
