Exclusive: Obama Explains Why His Campaign Will Wait for 'Toot'

Oct. 24, 2008 — -- Barack Obama is home today in Hawaii with his ailing grandmother rather than on the campaign trail because he fears she won't make it to Election Day.

Obama, who polls show is the front-runner in the election to become the leader of the free world, is likely doing chores right now for the woman he affectionately calls Toot.

"I want to give her a kiss and a hug," the Democratic presidential candidate told Robin Roberts in an exclusive interview for "Good Morning America" before heading for Hawaii to see his 85-year-old grandmother, Madelyn Dunham, the woman who largely raised him.

"And then we're going to find out what chores I can do, because I'm sure there's been some stuff that's been left undone," he said.

The Illinois senator took the unprecedented step of quitting the presidential campaign with less than two weeks to go so he could hurry home to the apartment he grew up in and see Dunhill. He rejoins the campaign Saturday.

Toot, which is short for "tutu," the Hawaiian word for grandparent, has been sick for a while and recently fell and broke her hip.

"Without going through the details too much, she's gravely ill," Obama told Roberts in an interview that aired today on "GMA."

Besides the hip, Obama said, "She had some other problems that were getting worse. You know, we weren't sure, and I'm still not sure, whether she makes it to Election Day.

"We're all praying and we hope she does," he said.

His grandmother's illness has turned Obama's stretch run for the White House into a bittersweet moment. He is leading John McCain, in most polls, yet also faces the possible loss of the most influential person in his life while he was growing up.

"One of the things I want to make sure of is that I had a chance to sit down with her and talk to her," Obama told Roberts. "She's still alert and she's still got all her faculties. And I want to make sure that I don't miss that opportunity right now."

Obama has also said publicly that he regrets not returning to his mother's bedside before she died of cancer, as he overestimated how much time she had to live, and he doesn't want to make the same mistake twice.
