Campaign Finance Reform Activist 'Granny D' Dead at 100

March 10, 2010— -- If nothing else, Doris "Granny D" Haddock was a fighter. From 1999 to 2000, when she was 89, she walked 3,200 miles across 12 states, fighting for campaign finance reform and against emphysema and arthritis along the way. She kept up the fight until her death March 9, 2010, at her home in Dublin, N.H. She died at the age of 100.

"Campaign finance reform is the most important subject that we have," Haddock, a grandmother of eight, told ABC News when she finished her march to Washington. "If somebody doesn't make a move to get it started, then it never is going to happen."

Granny D, as she was called by her friends and supporters, was born Jan. 24, 1910, in Laconia, N.H. She worked and raised her family during the Great Depression, and was later a designer for a shoe manufacturer in Manchester, N.H .

In 1960, she and her husband, Jim, helped to stop the planned use of hydrogen bombs in Alaska. Their actions saved an Inuit fishing village in Point Hope. She took up the cause of campaign finance reform in 1995, after the defeat of a bill sponsored by Sen. John McCain, R-Ariz., and Russ Feingold, D–Wis. -- their first attempt at a campaign finance bill.

On Jan. 1, 1999, just shy of her 90th birthday, Granny D began a walk across the country to highlight her passion on the issue. She walked 10 miles each day for 14 months, giving speeches along the way. "'Granny, you're walking for me.' 'Granny, I no longer have a voice, and I want us to have it back,'" she said voters told her during her march across the country. When she finally arrived in Washington, D.C., she was greeted by an estimated 2,200 supporters. Several dozen members of Congress joined her for the last few miles to Capitol Hill.
