There are plenty of things you can do with Obamacare and the King v. Burwell decision yesterday. First off, you can use Marbury v. Madison to discuss the powers of the Supreme Court. You could also talk about federalism and more specifically cooperative federalism since it take the state legislatures to agree to implement Obamacare. That, of course brings up the 10th amendment since health care is not mentioned in the Constitution. You could also mention the top clip above which looks at the impact this decision has on the 2016 federal elections. Finally you could discuss partisan media sources such as the Huffington (liberal) Post which is the middle video or Fox News (conservative) which is on the bottom.
