State-by-state breakdown of Obamacare's impact

States that fully embraced the President Barack Obama’s health care law’s coverage expansion are experiencing a significant drop in the number of uninsured residents, according to a major new survey released Tuesday. States whose leaders still object to “Obamacare” are seeing much less change.

The Gallup-Healthways Well-Being Index found an overall drop of 4 percentage points in the share of uninsured residents for states accepting the law’s core coverage provisions. Those are states that expanded their Medicaid programs and also built or took an active role managing new online insurance markets.

The drop was about half that level — 2.2 percentage points — in states that took neither of those steps, or just one of them.
