Honestly it seems like a mostly thankless job that doesn’t pay well. Why deal with the aggravation? And most of the time they aren’t in touch or can’t relate to the struggles of the common people and if they really analyzed things before jumping in they would see that following the will of the people would probably be determental to their own success. With that said, do they do it to insure the will of the people doesn’t get in the way of their success? That’s just messed but in most cases so is their performance in office.
