All you have to do to be an American is exist in America? Does the individual have a choice in the matter?....is there an opt out?
I'd say the illegals that don't plan on returning to Mexico or wherever are Americans.
If you are a foreigner who comes here with the intention of not leaving, I think you're an American the second you step foot on American soil.
But I still chose poor Americans for this poll... though I believe the basic needs of everybody should be taken care of... food, water, and access to shelter.
