Make it illegal for people from the same immediate family as previous presidents to be president.

I am 25 years old and since I was born there has been two Bush presidents, a Clinton, Obama and now there is a strong chance there will be another Bush or Clinton in office. I was raised to believe that everyone in this country has the chance to become President but when my entire life with the exception of Barrack Obama it has been two families running the nation. Does no one else see anything wrong with this? This country defines itself as a democracy but is it really a democracy when two families run the nation? I think it's time to wake up. I petition to make it illegal for people of the same immediate family to be president in order to have a real democracy.
