DURHAM, Ore. (AP) — After months of trying to get its problem-plagued online health exchange to work, Oregon on Friday officially gave up on the state portal and decided to switch to the federal website — the first state in the nation to do so.

An early adapter and early enthusiast of the Affordable Care Act, Oregon was once seen as the national leader in health care reform. The progressive state’s ambitious vision for its exchange, its colossal multimillion-dollar failure, and the inability to fix the glitch-filled site illustrate the complexity of the health care law and the challenges for states that decided to build their own exchanges.
