Less than a year old, President Obama?s signature legislative achievement heads under TIME magazine?s microscope this week:

While wholesale repeal is virtually impossible, there is no guarantee that the shaky coalition Obama glued together to get the landmark bill passed last year will hold. In the midterm-election campaigns, Democrats found themselves under fire for backing a new expansion of federal entitlements. Some of those who expect to face tough contests in 2012 may decide to hedge their bets on subsequent votes to defend or dismantle the law. One House Democrat, Dan Boren of Oklahoma, has already said he is “inclined to support the repeal.” Physicians’ groups, hospitals, insurers and drugmakers, which reluctantly got behind the measure last year, will stick with the law only if its implementation appears to be stable and predictable. Major legislative revisions, which are not impossible, may cause their support to evaporate. It is almost certain that the law will be changed before the 112th Congress adjourns next year.
