Dublin, N.H. ? “I am not a nice old lady,” Doris “Granny D” Haddock says, wheezing slightly as she walks up a road near her home. The 94-year-old relishes adventure and near-impossible challenges — once walking across the country despite emphysema brought on by a half-century of smoking.

Now Haddock has taken on another Herculean task: She is trying to unseat Republican Sen. Judd Gregg, one of New Hampshire’s most popular politicians.

Haddock embarked Thursday on a 200-mile walk through New Hampshire to promote her candidacy, sent off by a marching band and about 100 well-wishers. She plans to walk five miles each morning and campaign by car the rest of the day.

“If you want something done right today, you have to run for Congress yourself — or at least send your grandmother,” said Haddock, who has 16 great-grandchildren.

The Democrat insists she is no sacrificial lamb against the 57-year-old Gregg, a former governor whose campaign has about $2 million in the bank to Haddock’s $50,000.

She entered the race at the last minute after the expected Democratic nominee dropped out, leaving Gregg essentially unopposed in November in his bid for a third term. (Gregg has token opposition in the Sept. 14 GOP primary, while Haddock has none.)

Haddock vehemently opposes the war in Iraq, and calls Gregg “an enabler of George Bush’s neo-con scourge.” The daughter of a warehouse worker, she decries the flight of good jobs overseas that is making us “a nation of Wal-Mart greeters.”

“I am the angry grandmother come off my porch to ask young Judd what in the world he is thinking when he supports Bush’s military misadventures, supports the transfer of billions of our tax dollars to billionaires and supports the shipping of our jobs overseas,” Haddock said in announcing her candidacy this summer.

Gregg has not responded to Haddock’s attacks. “I’m going to run on my issues,” Gregg has said. “I don’t spend a lot of time trying to juxtapose myself with my other opponents.”

As Haddock begins her walk across the state, she is doing what she does best.

Five years ago, at 89, she walked across the country crusading for campaign finance reform, trudging through the Mojave Desert, Texas heat and the Appalachians in the thick of winter to reach Washington after 3,200 miles and 14 months. In 2001, she walked around the U.S. Capitol almost nonstop as the Senate debated — and ultimately passed — the McCain-Feingold campaign finance bill.

Her most recent exploit was traveling the country in a camper, registering women and minorities to vote.

On a recent morning she was out training for her walk, a wild turkey feather poking from her hatband. The emphysema slows her down, but Haddock says the adventure makes it all worthwhile.

“Walking across the country, that was not what you call easy, but I considered it my job,” said Haddock, a widow whose New England accent arrests listeners with its aristocratic inflection.

Her campaign is unconventional — some staffers live in tents on her property and her headquarters is her living room. But it got a big boost recently when Joe Trippi, Howard Dean’s Internet-savvy former campaign manager, began volunteering as Haddock’s principal strategist.
