HONOLULU - For the last 21 months, she has followed the odyssey of his presidential campaign like a spectator in a faraway balcony.
Nearly blind, she underwent a corneal transplant to see him on television. She reluctantly agreed to film a political ad when he needed to reassure voters about his distinctive American roots. She told him that it might not hurt if he smiled a bit more.
On Friday, Barack Obama -- a grandson, not a candidate -- spent the day saying goodbye.
He came to the Punahou Circle Apartments, a place of his childhood, where his grandmother Madelyn Dunham, who turns 86 on Sunday, lay gravely ill. For weeks, while not mentioning her illness while campaigning, he has talked to doctors and tracked her condition. After she was released from the hospital last week, he received word that he should not wait until after the election to make what he believes could be his last visit.
It was an unusual departure from the tug-of-war of a presidential campaign, particularly with 11 days remaining in the race. But it was a trip that his advisers said he told them was not negotiable. He missed his mother's death in 1995, a mistake he said he did not intend to repeat with his grandmother, who helped raise him and has been a stalwart force in his life.
"My grandmother's the last one left," he said. "She has really been the rock of the family. ... Whatever strength and discipline that I have, it comes from her."
His first visit lasted about 70 minutes on Thursday evening. He returned on Friday to the 10th floor apartment -- the place he lived between ages 10 and 18 -- which was flooded with flowers and well wishes from strangers who were introduced to her in Obama's first book, "Dreams From My Father."
Obama has reached the closing days of his run for the White House without holding a formal biographical tour. (In a candidacy built on biography, and criticized for its celebrity, his advisers believed that sticking to substance was a wiser course.)
