Surely ther is some gray in this situation its not totally black or white (Obama pun)
I see no reason to lie about a birth certificate and the conjecture as to why is getting out there ,but there is a lot of evidence that the birth certificate that has been posted is a lie
This article is very cleverly deceiving. Note that in the first paragraph the author did not say that McKinnon forged an Obama birth certificate and then daily kos post it this forgery. He said that McKinnon was able to forge birth certificate that are similar to the one posted on daily kos and that is a huge difference here. The author used those clever deceptive wording knowing that the people who are already bought on Obama Birth certificate conspiracy theory are not going to read this thing in any detail and assume that McKinnon forged Obama birth certificate.
By the way this guy McKinnon is now saying that he hired a lawyer to go after some internet blogs who are defaming him and accusing him of forging Obama birth certificate and that daily kos posted his forgery.
