Madelyn spoke about her grandson in a campaign commercial.
The BBC has more on the "central figure" in Obama's young life.
She and her late husband Stanley raised the young Barack in Hawaii for many years while his mother, who had remarried, lived abroad.
Known within the family as "Toot", a shortened form of the Hawaiian word "tutu" meaning grandmother, she gave him a stable home and the traditional American values brought from her own Midwestern childhood.
"Toot" was also in an ad for her grandson in April. Watch it here:
