Yes.
I believe that Obama has been secretive regarding his past. I believe he has lied about it. I don't buy the story he's told us about his parents. I don't buy the story about his education. I believe he's a sociopathic liar.
But the document looks legitimate, and the narrative that this is a grand conspiracy with forged documents is laughable. It reminds me of a buddy of mine who used to spend hours trying to convince me that the WTC towers were blown up and that a plane didn't hit the Pentagon.
