ACA-legacy or disaster?

Obamas's legacy holds in the balance as the administration tries to fix the problem with website. However there are other problems related to the policy that still need to be addressed such as will there be enough young enrollees, how about the people whos private insurance policies were cancelled, and data privacy issues. Even if the website gets up and running these are the policy problems that the administration must deal with.
On the poltiical front this could be a serious problem for democrats heading in to 2014.  A bill that the democrats defended and now privately worry could sink their chances of retaining control of the Senate. Also more importantly a contention big goverment is too big and inefficient to run public health policy. Obama is clearly an ideologue determined to put into reality his view of government. Other issues the administration has avoided thus far but healthcare is something that everyone can see and affects their pocketbook. 
Bill Clinton governed from the left in his first term but came to the center durng his second term by working with republicans to pass legislation and left office with a high approval rating.  So the question is will Obama allow congress to help revise the health care law for his signature legacy issue or will he push the liberal agenda back several decades by proving that a goverment takeover of healthcare.
