Donofrio has his own questionable, hysterical moments. I know, I watched it all unfold, as you did.
But, McCain clearly had and still has unresolved questions, as to whether he qualifies as a natural-born citizen. The very existence of SR.511, plus various Senate bills proposing Constitutional Amendment, to define children born abroad of military parents as natural-born citizens, both support such an argument.
That two citizen parents are a requirement for natural-born citizenship is not in dispute for John McCain. But, he was not born of the soil.
That born of the soil is a requirement for natural-born citizenship is not in dispute for Barack Obama. But, he was not born of two citizen parents.
So, Donofrio has had his highly public, nutty moments himself. He's also aligned with Democrats. That does not invalidate all points raised by him, though.
The same observation can be made regarding practically all so-called attorneys who have attained any level of notoriety, in association with lawsuits pertaining to Presidential eligibility.
I’ve read his stuff. SOme of it is great, some of it is not so great, IMO. Overall, I think his approach will be soundly defeated if his case is heard in court. HOWEVER, I do not waste my time and energy denigrating him. He is trying the best way he knows to get rid of the boy marxist. I wish him well. Also, his latching on to the Miss Tickly method of forcing the HI bureaucrats to cough up info on their statements and actions is very useful.
