But instead of serving as a national model, Oregon’s experience has emerged as a cautionary tale, inviting comparisons to technical glitches that have plagued other state-run portals and the federal government’s website for those states lacking exchanges of their own.

Oregon’s online exchange has remained inaccessible to the public, requiring the state to sign up applicants the old-fashioned way, using paper forms. This has made comparison shopping more difficult for consumers and severely slowed the enrollment process.

“Oregonians have questions,” said state Senate President Peter Courtney, a Democrat, in a written statement on Tuesday. “What went wrong with the rollout? How are they going to fix it? When are they going to get it right? Is the website contractor doing everything it can? Our people need to know.”
