Oh, I don't know, perhaps it comes from being on the same side of this issue as every single court ruling thus far, standing in agreement with every SINGLE member of Congress, with the former POTUS and VPOTUS, with every Justice of the SCOTUS, and the vast majority of lawyers, military officers, and Constitutional scholars.
If the candidate was not eligible, then someone will have to produce evidence supporting this allegation. Until that happens, everyone listed above will correctly recognize Mr. Obama as the legitimate President and the courts will concur. If evidence is ever presented, then the Congress could initiate impeachment proceedings, if they so choose. So far, no evidence, just a bunch of hoopla.
Or, to translate:
Don't you people understand that I'm imagining a bunch of stuff in my head! How can you possibly discount that in a legal proceeding?
I believe something like it is said in every case with a mental capacity judgment.
As every single court??? You think that makes you correct? Hahahahahahaha? Oh my, I should rest my case.
