Hillary Clinton-has she had a private sector job where she ran a company? Or managed a state, city or village?

Just trying to understand how she can possibly be qualified to even run for office of the President. Seriously, managing the US takes experience like that of a CEO- someone who has in their background, years of runnning a very complex "organization"- be it a company or major government entity. Hillary, along with several other candidates on both sides do not have any of this. How can one justify even defending the credentials of Hillary and the others who do not have any of the above mentioned atributes is totally beyond comprehension.
