'RomneyCare': A revolution that basically worked

In his critics' eyes, with the national health overhaul pushed through by President Obama. Republican Presidential candidate and former Massachusetts Gov. Mitt Romney has given up trying to distance himself from his own creation, though he rejects the comparison to "ObamaCare." The greater question now isn't whether the Massachusetts overhaul is fairly named as his -- it is -- but whether the innovative changes he pushed through have worked as intended. A detailed Globe examination of voluminous healthcare and financial data, and interviews with key figures in every sector of the healthcare system, makes it clear that while there have been some stumbles -- and some elements of the effort merit a grade of "incomplete" -- the overhaul has, after five years, worked as well as or better than expected.
