"With two more years of signups and tens of millions of people covered, it will be virtually impossible for Republicans to repeal the law. For this reason, Republicans are getting nervous. None of their dire predictions for year two are coming true. Premium costs have not skyrocketed; people are satisfied with the insurance that they purchased on the exchange, and the vast majority of those people are renewing their plans.
The media coverage and the endless drumbeat of right-wing negativity have combined to obscure the fact that the Affordable Care Act is popular with those who are signing up, and the law is proving that government can respect the marketplace and be a force for positive change. Republicans are nervous because deep down they know that the ACA is here to stay."
