Barack Obama: "My mother, when she was between jobs, contracted cancer," and she spent the last days of her life trying to figure out how to pay for care. "We've got to have a president who's willing to fight" the healthcare industry to make sure they don't have "veto power."

John Edwards: Obama's plan "just doesn't cover everybody." He complained the politicians have talked about health care too long without standing up to insurance companies and drug companies.

Hillary Clinton: She said it is "a national disgrace" that people like those in the videos still struggle to get the care they need. Clinton said everyone should be covered.
