In Oregon, incumbent Ron Wyden attempts to run from the unpopular health care bill he voted into law last year.  The Wall Street Journal reports:  

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… Mr. Wyden should have known better than to vote for ObamaCare given his market instincts and health-care experience… These practical realities aside, Mr. Wyden’s move may be more important as a political signal. Mr. Wyden is running for re-election this year. And while he is now well ahead of GOP challenger Jim Huffman, in a year like this one he has cause to avoid becoming Barbara Boxer or Patty Murray, who may lose because they’ve remained liberals from MSNBC central casting… On ObamaCare, Democrats are having the first political second thoughts, at least in this election season. Mr. Wyden is essentially saying that what his party passed is not acceptable, and if such thinking builds, opponents may have a real chance to replace ObamaCare with something better.
