Also known as Obamacare, the Affordable Care Act (ACA) has been the center of the healthcare dispute. The ACA has three important parts: make affordable health insurance to everyone (the mandate), expand Medicaid (people who can't afford healthcare), and create new healthcare delivery methods to drive down the cost of healthcare. Democrats love it, and Republicans hate it. Why? Because too much government and favors the poor more than the rich and better-off.
