I think that Teresa Kerry hurt her husband’s campaign and I think that Mrs.Obama will do the same.Unless they can keep her quiet, as they seemed to have done recently,she will be a real minuis for him which is fine by me.
All it will take is one appearence by Jesse Jackson and 2/3rds of Obama’s followers will flee...
I suspect Oprah Winfrey was tapped to support the Obama campaign so that she could basically be the "real" Mrs. Obama in the minds of voters.
