From the Motley Fool:
"Simplified, Obamacare (the Affordable Care Act/ ACA) does a few big things:
Prevents insurance companies from denying customers for pre-existing conditions.
Allows young adults to stay on their parent's insurance until age 26.
Limits age-rating, or charging premiums several times higher for older customers.
Eliminates lifetime insurance caps and restricts annual limits.
Restricts how much insurance companies can spend on non-medical costs (overhead).
Mandates that everyone acquire health insurance by 2014 or face a tax, offering subsidies or Medicaid for those who can't afford it."
"The measuring of political wins and losses misses the point altogether. The winners here are the nearly 50 million Americans who don't have health insurance. They're the majority of personal bankruptcy cases linked to medical bills, and those who couldn't quit their job because they can't afford to lose employer-provided coverage."
"Mitt Romney has vowed to repeal the ACA if elected president. One of the biggest complaints about the ACA is that it causes uncertainty. No one knows what might happen next, or what health-care costs will be a year or two from now. Alas, that hasn't gone away."
From this I would interpret that if you are unemployed with no income, you can fall back upon Medicaid for Health care. Of course, this probably means long lines, lots of paper work and probably not the best quality healthcare.
