President Obama is set to speak this morning about how the health-care law is cutting premiums for millions of Americans. His remarks will focus on a small Affordable Care Act provision known to health wonks as the "medical loss ratio." Rolls right off the tongue, right? Maybe not.

And it's the provision that the White House is homing in on, in arguing that the health-care law will make health care cheaper for American families.
