I do, although, my reason is probably somewhat less thought out than those who are experts on the situation. If there is nothing to hide, I believe he would have revealed his birth certificate months ago. Part of me believed he had a legitmate birth certificate and was waiting for Rush, etc. to comment so he could discredit them by saying “look, they’re racists, they’re questioning this” blah blah blah. But now, not only has a birth certificate not been released; there are questions about his “alias” Soreto in Indonesia, lying on his bar application, and apparently college scholarships/grants/$ he received. Add to it, Gibbs’ comment about it being proved ad nausem, which it has not, my “spidey” senses are tingling so to speak.
If the BC was legit, his current tanking poll numbers would provide perfect motive for him to whip it out. But he hasn’t. And you can read Gibb’s’ face like a book.
