Why are Republicans still fighting it? A history of the conservative strategies to repeal or weaken the Affordable Care Act, and what’s left in their playbook:

“The right’s actuarial guerrilla war begins with the underlying reality that hardly anybody knows about the exchanges. Polls show that fewer than six in ten Americans even know the law still exists, with the remainder believing it’s been repealed or struck down, or unsure. Of those aware that the law remains in effect, few understand how it works. Yet to succeed, Obamacare requires a critical mass of uninsured Americans not only to grasp what the law does but to act on it.”
