Yes. They are. However, they need proof that they were born here. They would need a birth certificate or something. If they don't have the proper evidence that they were born here (no matter if they are Native American) they can't be President.
Absolutely yes. If they are 35, born on US soil, born to one or more US naturalized citizens on US held soil such as an embassy or military installation, or born to two naturalized citizens on foreign soil, and meet the other couple of minor qualifications as set forth in the Constitution.
Yes and it's insulting to them that an African was allowed to be President before them. So long as they don't turn America into a Casino I'd consider voting for an American Indian.
illegal alien hmm thats a tough one.
wrong culture possibly
too sensible yes for sure.
really ,what a daft question
