We know Obama is a natural born citizen by place of birth.
A Birther named Stephen Tonchen has a paper making the rounds, arguing that Obama is ineligible to be President due to his
father's citizenship. Tonchen writes in a reasonable-sounding way, mostly, in arguing his points.
This is pretty much their final argument, since everything else they've put forth falls easily apart and court case upon court case have been dismissed. I am posting it here, because it is nuanced enough that it's not a simple one to debunk.
It might be worth educating ourselves about the topic, I think, so for those interested in learning more, here is the current debate.

Obama Presidential Eligibility - An Introductory Primer
Last revised: June 5, 2009
Abstract
Despite the mainstream news media's silence regarding this matter, an increasing number of Americans are concerned that Barack Obama might not be eligible, under the Constitution, to serve as President.
According to the U.S. Constitution, an individual born after 1787 cannot legally or legitimately serve as U.S. President unless he or she is a "natural born citizen" of the United States.
Among members of Congress and the mainstream news media, the consensus of opinion is that anyone born in the United States is a "natural born citizen". However, when we researched this issue a bit more carefully, we found that the consensus opinion is not consistent with American history.
In Minor v. Happersett (1874), the Supreme Court said that, if you were born in the United States and both of your parents were U.S. citizens at the time of your birth, you are, without doubt, a natural born citizen. In the same case, the Supreme Court also said that, if you were born in the United States and one of your parents was not a U.S. citizen when you were born, your natural born citizenship is in doubt. So far, the Supreme Court has not resolved this doubt because, until now, there has never been any need to do so.
With only two exceptions, every American President, who was born after 1787, was born in the United States, to parents who were both U.S. citizens. The two exceptions were Chester Arthur and Barack Obama. When Chester Arthur ran for office, the public did not know about his eligibility problem. Only recently did historians learn that, when Arthur was born, his father was not a U.S. citizen. The 2008 election was the first time in history that the United States knowingly elected a President who was born after 1787 and whose parents were not both U.S. citizens.
Barack Obama publicly admits that his father was not a U.S. citizen. According to Minor v. Happersett, there is unresolved doubt as to whether the child of a non-citizen parent is a natural born citizen. This doubt is not based on the imaginings of some tin-foil-hat-wearing conspiracy theorists on the lunatic fringe of society. This doubt comes from what the Supreme Court has actually said, as well as a variety of other historical and legal sources which are presented and discussed here.
This Primer introduces and explains the Obama Eligibility Controversy, in question-and-answer format, for a non-technical general audience. We've double-checked the facts presented here, and we've cited the sources of each fact.

Response to Eligibility Primer (Part 1) - June 20, 2009I have come to realize that there are two debates on the question of presidential eligibility and the definition of “natural born citizenship”, and some of the more thoughtful people on each side are debating different things. One debate thesis may be summed up this way:
The Constitution does not define “natural born citizen”, nor is it defined in legislation. The U. S. Supreme Court has never decided the question of the relationship of parentage to natural born citizenship. The uncertainty should be resolved.
The second debate thesis might be summed up this way:
Based on common law principles, and supported by numerous authorities, one may conclude with a high degree of certainty that natural born citizens of the United States are those born within its borders except the children of ambassadors.
Folks like Ken Dunbar and Stephen Tonchen (the author of the piece to be discussed here) are debating the former, and this web site is largely geared towards investigating the latter. If debating the first question, then one might say that Barack Obama’s eligibility is “unproven”, but when debating second one will conclude that it is “proven”.
