When were they ever our representatives? They got into politics and government in the first place in order to to get what they want, namely the power to run other people's lives, not what we want. I knew some of those kind of people way back in high school and college, and you probably did too. They were pompous, insufferable, self-appointed control freaks then and they still are today. If they actually worked to put the Constitutionally guaranteed rights and overall welfare of the people before their insatiable lust for power and their perverted ideas of what the US should be, the nation wouldn't be in the mess it's in now. Once they get our votes and take office they couldn't care less what we want until they need our votes again.
It probably wouldn't do any good to throw them all out and start over again, although that wouldn't be a bad idea. The people now in government who want to run our lives would just change places with another gang who also want to run our lives. I believe that something is wired up incorrectly in the psyche of people who want to run other people's lives, and IMHO that faulty wiring is responsible for 98% of the problems with government at every level from the county commission board to the White House.
I worked for a candidate once who did win. That candidate was bossy and difficult. I agree with you: it takes that kind of person to run. A “normal” person would not be like that, thus they wuld not win. I guess there is no such thing as “Mr Smith goes to Washington”
