Yes, what I think most are missing, but surely not you, is the possibility BHO is hiding the fact his parents were not married at his birth.
If so, he is guaranteed a White House berth. It will be perceived by most as an attempt by him to shield his children (especially daughters) from uncomfortable reality.
If this proves the case, then his polls will soar since the voters will respond to his “shield the daughters” response rather than any effort to truly fool others.
In the meantime, it is important to recall when President Clinton was being exposed as having fellatio performed by a female intern, his polls went up. They went up for the same reason—many saw his lies as attempts to protect Chelsey and Hillary. If our righteous Republicans would have just given him a censure they might have avoided the wrath that brought down Bob Barr, Robert Livingston Henry Hyde et al. Even Gingrich was implicated as having sex with an aide, but he avoided this conclusion by resigning from Speaker of the House. To this day Gingrich denies he responded to Larry Flynt’s efforts to expose Republicans purshing Clinton as being no better than he.
BHO will have a perfect weapon with this revelation to portray his critics as right wing, paranoid flakes and, subsequently, dismiss all the other rumors (many with substance).
I don’t think BHO has ever hidden the fact that his parents were not married. He has made much about his Kenyan kinfolks and I think one of his books hinted at this omission.
