Republicans and other anti-Obamacare persons and organizations are fighting an uphill battle that they are likely to lose.
Obamacare, also known as the Affordable Care Act or ACA, only needs to succeed in one state. This state will serve as the model to which other states must follow to ensure the goals of Obamacare are attained. With the experiences of Massachusetts, California and New York reporting favourable results in bringing costs down, enlarging the number of people covered and making it easier for US residents to obtain health coverage, the task to successfully prove that Obamacare is a failure is remote.
For the foes of the national health care plan to prove that Obamacare is not a workable solution, it must be shown that failures in the system are not due to implementation issues created by opposition forces and Republican governors who don't like the plan for whatever the reason. It won't be good enough to just show the plan failed in a particular state. If a governor has refused to expand medicare/medicaid or not made an exchange system available to the residents, then one cannot blame Obamacare for it not meeting it's objectives in the respective state.
And the reality is, as people come to learn the FACTS (something the right side of the political spectrum seem to shun), they will come to like the national medical care plan. And those who are being barred from its access will demand it be made available to them. When the upside is easier access and savings of $6,000 per year or more, it may even be worth moving for these benefits - a potential headache for businesses located in these lagging states.
My prediction is that by the 2016 Presidential election, there will be a change in conversation and all politicians will be talking about ways to improve Obamacare and how to bring the rest of the states on board. The fight to repeal it will be over.
