Jindal (and Marco Rubio) are targets of some of the more monumentally idiotic birther claims:

But, as Romney may learn as he winnows the field of candidates to serve as his running-mate, two of the individuals most often named as being under consideration — Louisiana Gov. Bobby Jindal and Florida Sen. Marco Rubio — have been targeted by a certain strain of birthers who contend that neither man is constitutionally eligible to serve as president or vice president because, while they were both born in the United States, their parents were not U.S. citizens at the time their sons were born.

The claim is based on a tendentious and distinctly minority interpretation of what the Founding Fathers meant by “natural born,” when they wrote, in Article 2, Section 1 of the Constitution, “No person except a natural born citizen, or a citizen of the United States, at the time of the adoption of this Constitution, shall be eligible to the office of President …”
The ordinary reading of “natural born,” is that it means the same as “native born” — and would count someone born in the United States as a citizen regardless of the parents’ citizenship status.

Among the most prominent of these is Joseph Farah, editor and CEO of the website, WolrdNetDaily, who wrote last August, “Two candidates for the job (vice president) are mentioned over and over again — two wonderful, charismatic public servants whose only problem is they are not constitutionally eligible to be president.

“They are Sen. Marco Rubio of Florida and Gov. Bobby Jindal of Louisiana.
“Don’t get me wrong. I like both of these guys. If I were eligible to vote in Florida or Louisiana, I would vote to re-elect them. I would support either one for almost any job in America. But there is one job for which they are, by chance of birth, 100 percent, totally and inarguably ineligible to hold office — and that is the presidency of the United States.

“Why? Because both are sons of parents who were not U.S. citizens when they were born. It’s just that simple. To be a natural born citizen means to be the offspring of U.S. citizen parents at the time of birth.”
