So long as politicians do their duty by representing the interests of those that elected them, they are fulfilling their end of the covenant with the people. To demand the financial records of candidates will not offer more than crude snapshot of one aspect of their lives, not giving the desired insight into their character, while massively intruding on the politician’s personal life. As is often the case here the right to know conflicts with the candidates right to privacy. Of course it is right to know if a candidate pays his taxes, but do they need to know every expense he has incurred over the last few years or how much a candidate earned years ago?
