President Barack Obama accepted his party's nomination for another term by framing the election as a choice over whether voters value his signature health care law, among other policies.
Obama credited the voters who elected him the first time with enactment of the Patient Protection and Affordable Care Act.
"You're the reason there is a little girl with a heart disorder in Phoenix who'll get the surgery she needs because an insurance company can't limit her coverage," he said about the law's popular ban on lifetime limits. "You did that."
Obama also attacked Republican presidential nominee Mitt Romney for proposing to repeal the health care law and to add a subsidized private insurance option to Medicare for future beneficiaries who enroll in 10 years.
