Mitt Romney says that the passage of healthcare reform legislation represents an "unconscionable abuse of power." Romney, however, promoted and endorsed a remarkably similar plan while he was the governor of Massachusetts.
Romney is clearly trying to position himself for the Republican presidential nomination in 2012. In order to do so, he has decided to condemn the healthcare legislation, even though the national plan and the Massachusetts plan he endorsed share many central components.
I doubt that Republicans will allow Romney to remake his image. They already ridicule the Massachusetts plan as "RomneyCare." He will likely lose in 2012 because of his "liberal" past.
