What should be the motive for becoming a States-Person?

Do individuals who seek political office have a reason or motive for seeking Office? Obviously, they must; but, what should that motive be? Of course, all Politicians and States-Persons come from the People who constitute that particular Nation. The individual at the Top is always a 'member' of the populace. But, what political values should such an individual 'possess' or what political values can justify the assumption of the political position? Of course, any 'political position' is a position of Power, because it purports to Rule, Govern, or Dictate. If the Top of government dictates, it's a Dictatorship and it dictates, period. No other considerations need to be addressed. If the Top rules, it Rules, period. But, if the Top Governs, it must have a 'platform' and a general idea of what it means 'to govern'. In a Democracy, the individual who ascends to the Top must do so to govern the People at the Bottom. There should not be any other motive for purporting to govern. The only reason or motive for 'running' for Office in a Democratic government should be to implement, or better perfect, democracy. This already requires the individual to be less selfish and to act in a 'representative' manner; in a selfless manner. This necessity should compel the candidate to embrace democratic, political values and to distance him/herself from economic values; simply put, from money as a motive or reason for seeking political Office. How is that to be done? By implementing policies and Laws that protect the Freedom and Equality of the individual at the Bottom of Government. A States-person protects the Freedoms and Equalities that allowed him/her to ascend to the position of power. This is already selfless. But, some of the policies and Laws already on the books have been changed and attenuated, in a manner designed to substitute economic values; i.e. , money, in place of political values, viz. Freedom and Equality. Democratic values must be strengthened, even if it means to change the 'changed' Law and Policies back to what they were and to do away with Citizens United. Where are our States-Persons?
