Can an ordinary, everyday person become President?

I am thinking about running for President of the USA.  However, I wonder if it is possible for an everyday, regular, ordinary person to become President of the nation.  I mean everybody who is even considered for the job is a millionaire, is well connected with corporate and Wall Street giants and is approved by the major political and social elites.  But what about the everyday person?  Are they locked out of the job of serving their country because they are not rich, politically connected and socially elite?  That’s a shame.  Maybe there is hope in the Tea Party Movement which is ordinary, regular and everyday people attempting to make a difference in the political life of the nation they love!
