It was just over a year ago that the Supreme Court upheld the Affordable Care Act. The Advisory Board puts the space between then and now in this helpful graphic.

The Affordable Care Act has become more sweeping since the Supreme Court ruling. The number of states backing the Medicaid expansion has more than doubled. Accountable Care Organizations, the health law program meant to move away from paying doctors for volume to reimbursing on value, has tripled in participation.

Republican opposition, in Congress at least, has faded, with notably fewer votes to overturn a part of the law in the past year.

What hasn't changed: Public opinion. The split on the health care law, tilted slightly negative, has remained constant for just as long as the Affordable Care Act has been law.
