Donal Trump has really rattled the liberal mainstream media. They are staring to call for repeal of the "natural born" clause of the Constitution. Amending the Constitution is a very difficult and time consuming process. It would be much simpler for them to call on Barack Obama to release all his records and put the issue to bed. Liberals aren't following that strategy because they fear "birthers" are right and Obama isn't Constitutionally qualified to be President.
PBS' Jon Meacham claims we should allow the children of immigrants to run for President. Barack Obama's father wasn't an immigrant. He was a foreign national living in this country while pursuing an education. The Constitution did not define "natural born." Most historic definitions of "natural born" require birth on this soil from citizen parents. Obama can never meet that requirement. His father was a Kenyan citizen and British subject. The U.S. Federal Courts need to define "natural born" more clearly, but they won't consider Obama's eligibility. No court has ever ruled Barack Obama is eligible to be President. Instead, courts are dismissing the cases on grounds of "lack of standing" because no harm was done to the plaintiff by Obama being elected President. They even dismissed a case where Presidential candidate Allen Keyes was a party. Apparently, the court didn't think he had a chance to win even if Obama was disqualified. Under the severe "standing" definition federal courts are now using for lawsuits relating to Obama's eligibility, John McCain may be the only person in the country who would meet their definition. McCain's "natural born" status has also been questioned (born in Panama Canal Zone) and he will never file a lawsuit.
Update: A commenter over at American Thinker made an interesting observation. When Jon Meacham advocated repealing the NBC clause so children of immigrants can run for President, he admitted that just being born on US soil isn't enough to make someone a natural born citizen. Barack Obama isn't a NBC by this reasoning because his father wasn't a U.S. citizen. Meacham must be very rattled to have let that slip out.
