What is Obamacare?
Actually, there is nothing called Obamacare - this was meant derisively by the GOP, who now can sneer at a law that is upheld by the Supreme Court and remains the law of the land. And, of course, the father of Obamacare - Mitt Romney - can talk a lot about how evil it is, except for of course he enacted the exact same thing in Massachusetts to great success.
But people talk so much crap about it, what is it really? I certainly haven't read the entire bill, and neither have you, I suspect.
Here then, is a great chart - and, for all the people benefitting from the things below, remembering that it's "Obamacare" and not the "Affordable Care Act" will, I suspect, be a net positive for our President.

Thanks to The Other 98% for this handy chart.
