Why do our politicians know less about our US Constitution than our average citizens?

Mark Twain once said: "fewer things are hard to put up with than the annoyance of a good example".I think with the politicians it's a classic case of maintaining self-interests at the expense of representing their electorate or constituencies.They seem to be more interested in re-election and courting lobbyists, while The USA is in recession with unemployment, high interest rates, inflation and foreclosures are all impacting on the country.They can get around this lack of knowledge by relying on the party aides, PR staff and speech writers to help them out.
