What can our legal system do to Obama if it can be shown that he is a presidential imposter and what can it do those who knowingly supported this conspiracy?
I don't know but I'd be a big fan of the "French Haircut" for everyone complicit in this particular case.
Your question is good but I think a better question would be what will the legal system do and that answer is nothing leaving a very slippery slope for those of us who are deeply concerned about our constitution.
