I want to know the answer to the following question:
What article, section, and clause of the Constitution requires U.S. presidents to be natural-born citizens?
All the background I'm provided with is that "Columbia University law professor Michael Dorf observed that Schwarzenegger's possible lawsuit could ultimately win him the right to run for the office, noting, "The law is very clear, but it’s not 100 percent clear that the courts would enforce that law rather than leave it to the political process."". Is that enough to answer the question?
