Most Democrats have come to understand that they can't run on ObamaCare, but few have the temerity of Ron Wyden. The Oregon Senator is the first to break with the policy underpinnings of the bill he voted for.

Last week Mr. Wyden sent a letter to Oregon health authority director Bruce Goldberg, encouraging the state to seek a waiver from certain ObamaCare rules so it can "come up with innovative solutions that the Federal government has never had the flexibility or will to implement."

One little-known provision of the bill allows states to opt out of the "requirement that individuals purchase health insurance," Mr. Wyden wrote, and "Because you and I believe that the heart of real health reform is affordability and not mandates, I wanted to bring this feature of Section 1332 to the attention of you and the legislature."

Mr. Wyden should have known better than to vote for ObamaCare given his market instincts and health-care experience. Even so, the price for his support included the Section 1332 waivers that he is now promoting. In addition to the individual mandate, states may evade regulations about business taxes, the exact federal standards for minimum benefits, and how subsidies are allocated in the insurance "exchanges"—as long as the state covers the same number of uninsured and keeps coverage as comprehensive.
