The individuals bringing these suits, if heard, will be able to subpoena documents and witnesses. This is the only way, absent a guilty plea, anyone presents evidence in court. No one will be forcing Obama to prove himself a citizen.
Point three is moot.
We know that Obama has a US Passport, courtesy of a little scandal a few months where a contractor poked into the passport files of Obama, Clinton and McCain. If Obama had presented fraudulent document to get a passport, there’s got to be a federal crime in there. That would be serious enough for impeachment, I think. But before ANY of that could happen, there would have to be some evidence of the crime. And there isn’t any, zip, zero, zilch. (Granny Sarah did not say the president elect was born in Kenya, she said “my son...Obama” was. Go read Berg’s transcript.)
So if there is no evidence, why are we having this conversation in the first place? Answer: Hawaii is not really a state.
