No, Madelyn Dunham is 85 and living in Honolulu, reportedly in the same apartment high-rise building where she raised Obama from age 11 to 18. She has kept totally out of the campaign limelight and refused virtually all interview requests, whether by her preference or not.... certainly the Obama campaign has been determined to run him entirely as a “black” candidate and not as a true bi-racial candidate.
Madelyn Dunham is really the only grandma he ever knew, but the campaign has trotted out a bogus Kenyan grandmother to fill out his fictional stories.

Good. Assumptions are bad things. The tone of much of the campaign is that she was dead--obviously he is running away from her to the extent practical.
85 now; Obama born 47 years ago when she was 38; her daughter was 18 and thus born when she was 20. All fits. 85 is not too old. And she might know something you could get out of her in a deposition if necessary.
