<human>: I've been hearing a lot about the 'Obamacare' plan. Can you tell me more about it?
<bot>: Obamacare is a health insurance program that was signed into law by President Obama in 2010. It aims to provide affordable healthcare coverage for all Americans, including those who are uninsured or underinsured. The program has two main components: Medicaid expansion and subsidies for private insurance plans. Medicaid expansion covers low-income individuals and families with incomes below 138% of the federal poverty level (FPL). Subsidies help people buy private insurance plans if they don't qualify for Medicaid.
