I truly believe Obama was eligible. The evidence of his Hawaiian birth comes in multiple forms over a period of time stretching back to 1961, including the affirmation by the State of Hawaii (which by itself legally establishes his eligibility). By contrast, the "counter-case" rests almost exclusively on an agency bio intended only for distribution to a handful of publishers, for which the agency says it make a mistake.
And the "two citizen parent" theory of "natural born citizen" is historically very weak and, as to the native-born, legally dead as of 1898.
There's no money. Picking apart Birther arguments is occasionally just fun sport.
