GRAND JUNCTION, Colo. — Now, it's personal.

President Obama invoked his own anguish over the death of a loved one as he challenged the debunked notion that Democratic efforts to overhaul the nation's health care would include "death panels."

"I just lost my grandmother last year. I know what it's like to watch somebody you love, who's aging, deteriorate and have to struggle with that," an impassioned Obama told a crowd at a town hall meeting in Grand Junction as he spoke of Madelyn Payne Dunham. He took issue with "the notion that somehow I ran for public office or members of Congress are in this so they can go around pulling the plug on Grandma."

"When you start making arguments like that, that's simply dishonest — especially when I hear the arguments coming from members of Congress in the other party who, turns out, sponsored similar provisions," Obama said yesterday.

In a debate in which he often sounds professor-like, Obama spoke with a rare bit of emotion that seemed to counter that of vocal health care opponents as he referenced the grandmother who helped raise him in Hawai'i and who he called "Toot."

Dunham, who lived in Makiki, died of cancer at age 86 on Nov. 2, two days before he won election to become the nation's first African-American president.

He talked about her death while answering a question about misinformation being spread about Democratic health care efforts during a town hall style gathering in a high school gymnasium.

"Health care is really hard. This is not easy. I'm a reasonably dedicated student to this issue. I've got a lot of really smart people around me who've been working on this for months now," he said. "There is no perfect painless silver bullet out there that solves every problem, gives everybody health care for free. There isn't. I wish there was."

But he said that because there's no perfect solution to solving health care, opponents "start saying things like we want to set up death panels to pull the plug on Grandma."

The president is seeking to put to rest claims that the health care overhaul he seeks would set up "death panels" to rule on life-sustaining care for ailing seniors. It would not, and Obama has stressed that point repeatedly over the past week.

Obama reiterated his contention that the Democratic health care legislation would not create "death panels" to deny care to frail seniors. Obama has explained that the provision that has caused the uproar would only authorize Medicare to pay doctors for counseling patients about end-of-life care, living wills, hospice care and other issues, if the patient wants it.
