This is a good but slightly confusingly phrased question.
In theory the citizens have the right to vote etc, in practice this is often a sham because people vote along tribal lines. In most constituencies of the UK for instance a monkey would be elected if it wore the right colour rosette (Blue for the Nasty Party, red for Tory Lite and Yellow for the Banana Bunch....). This means that many politicians can largely ignore the public. Furthermore the parties are so similar in policy and outlook that the only radical choice is a fringe party: my current choice would be the Raving Monster Loony party if I lived in England, but I will vote SNP till Independence is achieved.
Here in the UK we have seen so many non-sexual scandals involving our elected representatives and the government ministers picked from among them that it does seem reasonable to assume a successful politician is bent either for themselves or for their party until the reverse is proven.
It does often seem that our democracy is three wolves and a sheep voting on what to have for dinner and also what is on the proposed menu.
So while it is true to say we get the politicians we deserve, and studies show people vote for someone seems like them, this does not make us fraudsters, since to a large extent whoever you vote for the government gets in. We have to vote for the candidates picked by the local parties and do not have a "none of the above" box on the ballot paper. One excellent suggestion I heard was, if you have no candidate you want to vote for always vote for someone other than the one in office.
It is also true that the system tends to make honest people corrupt once they enter politics, and that there are insufficient safeguards to make sure they act honestly. But if these safeguards were in place then only people who loved power would stay in the game.
