President Barack Obama touched a chord during the health reform crusade when he remembered and agonised about his grandmother's death in the past year.
On a western tour mixing high-stakes politics with stops in majestic national parks, Obama said Saturday he was fighting a battle of hope over fear against critics who want to thwart his reform drive and stall his presidency.
Obama debated several skeptical members of a Colorado crowd, and fired off high-octane rhetoric reminiscent of his 2008 campaign.
"Because we are getting close, the fight is getting fierce," Obama told a town hall meeting of around 1,600 people packed into a high-school gym here, accusing critics of trying to scare the American people.
"These struggles have always boiled down to a contest between hope and fear," he said, referring to past presidents' crusades for pension and health care reform.
Obama also took another swipe at Republicans who have claimed his plans would include a "death panel" to make fateful decisions to deprive terminally-ill elderly patients of expensive treatments.
"What you can't do, or you can, but shouldn't do is say things like we want to set up death panels to pull the plug on Grandma," Obama said.
"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."
Former Republican vice-presidential candidate Sarah Palin and other Republicans claimed death panels were included in draft Democratic legislation, but the bill would simply allow federal funding for counselling about end-of-life care.
