I would imagine that the vast middle, the independent voters that generally determine the elections, will see the merits of the program and reward Democrats for their courage.
Again, I think if this is how things play out, then you'll see Democrats rewarded politically for their vision. It could be a political reward that lasts for a generation, much like the reward Democrats received from the FDR era.
As I said above, the White House put the insurance companies in their pocket as the first order of business.
