Two things....
First, I sincerely wish that stories about these children would go away. Obama himself has said many times, over and over, to leave the families out of this grinder, especially the children. It isn't right, nor is it fair to a 17 year old, to trot out her life onto the national stage, no matter how good or bad that life is.
That being said, I would venture to guess that were Barack Obama to have had a teenage daughter in the same situation, this election would be OVER.
That is the sad state of the electorate these days.
