OK, this is what it boils down to:
Justices to tackle epic debate over constitutionality of health care reform - CNN.com
Debate comes down to four key issues
Despite its complexity, the high court has narrowed its focused to just four key issues:
One: Constitutionality of the individual mandate (also known as the "minimum coverage" requirement), the key funding provision.
Two: Whether the individual mandate is a "tax," thereby limiting authority of the courts to immediately decide the mandate question.
Three: Whether other parts of the law can survive if the mandate is struck down.
Four: Federal vs. state conflict over expansion of the cooperative Medicaid program.
It is the "individual mandate" that has sparked the most controversy. It requires nearly every American to purchase some level of insurance or face a tax penalty of up to about $700 a year.
And, it's not three FULL days of oral arguments. It's 2 hours per day.
