>>Now, consider Marco Rubio. His parents were resident aliens when he was born in 1971, seeking and soon to receive their status as naturalized U.S. citizens. Under the Fourteenth Amendment, “all persons born...in the United States and subject to the jurisdiction thereof, are citizens of the United States and of the states wherein they reside.” This “subject to the jurisdiction thereof” clause shows why Rubio is — and, very likely, why children of illegal aliens are not — a “natural born citizen of the United States.”<<

“why Rubio is — and, very likely, why children of illegal aliens are not”
See that “likely” in there? That’s the kicker. Since the Supreme Court hasn’t ruled on this particular issue, all people can do is bat around how they “likely” would rule if it came up.
