So long, Toot. You did good.

Barak Obama's grandmother died today.

Barack Obama's grandmother, whose personality and bearing shaped much of the life of the Democratic presidential contender, has died, Obama announced Monday, one day before the election. Madelyn Payne Dunham was 86.

Obama announced the news from the campaign trail in Charlotte, N.C. The joint statement with his sister Maya Soetoro-Ng said Dunham died late Sunday night after a battle with cancer.

"She's gone home," Obama said as tens of thousands of rowdy supporters at the University of North Carolina-Charlotte grew silent in an evening drizzle.

"And she died peacefully in her sleep with my sister at her side. And so there is great joy as well as tears. I'm not going to talk about it too long because it is hard for me to talk about."

But he said he wanted people to know a little about her — that she lived through the Great Depression and two World Wars, working the second on a bomber assembly line with a baby at home and a husband serving his country. He said she was humble and plain spoken, one of the "quiet heroes that we have all across America" working hard and hoping to see their children and grandchildren thrive.

"That's what we're fighting for," Obama said.

Thank you for raising him so well, Mrs Dunham. You've given us all a wonderful gift. We'll take it from here.
