Ay, there’s the rub.
Nope, Obama hasn’t established his eligibility.
But... No President ever has (at least to my knowledge).
There is no established legal requirement or process that specifies how a candidate should demonstrate eligibility and to whom proof should be shown. This is a major hole in the process, IMHO. And one that needs serious correction.
That said, I’d ask you to consider whether the efforts to get states to pass the necessary legislation are helped or hindered by attention whores like Orly Taitz or retarded theories which claim that Obama’s name is really “Steve”.
