The comments at your link are frightful
The comments at the link are representative of why "Obama" was allowed, and is still being allowed to happen. They're just talking now, but if "Obama" were to be exposed publicly and forcibly removed from office, those commenters and at least 42 million other people would rampage, wrecking large amounts of our biggest cities and leaving us vulnerable to exploitation/attack by our enemies.
The NSA (yes, that NSA) had to have had heart-to-heart talks with all of Congress, the judiciary (as necessary, and especially SCOTUS) and the heads of the biggest media companies to not "go there" on the subject of eligibility. EVER. Nothing else explains the statistical improbability of there being zero people in positions to be able to do anything about the usurpation actually speaking out.
