HONOLULU (AP) - Democratic presidential candidate Barack Obama says he's not sure his gravely ill grandmother will live to see Election Day.
Obama is in Honolulu to visit Madelyn Dunham, who helped raise him. She turns 86 on Sunday.
The Illinois senator says he left the campaign trail with less than two weeks remaining before the election because his grandmother is ill but alert.
Her brother has said she recently fell and broke a hip.
In an interview on ABC's Good Morning America, broadcast today, Obama says the family is praying she makes it to Election Day but they're not sure she will.
Obama has said he missed a chance to visit his mother just before she died of ovarian cancer and he didn't want to repeat that mistake.
Obama stepped off his campaign jet alone laat night, taking a limousine directly to his grandmother's Makiki apartment. He was with her for about an hour before going to a Waikiki hotel for the night.
The candidate is set to fly off this evening to return to the campaign tomorrow in the battleground state of Nevada.
Obama so far has not spoken with reporters in Honolulu and plans no public appearances during the solemn visit.
He has said his grandmother suffers from osteoporosis.
