The U.S. Supreme Court has once again ruled in favor of the Affordable Care Act, this time upholding the law’s establishment of subsidies and exchanges. Here are some of the highlights from today's ruling.

1.  The vote was 6-3: Chief Justice John Roberts, along with Justices Anthony M. Kennedy, Ruth Bader Ginsburg, Stephen Breyer, Sonya Sotomayer and Elena Kagan voted to uphold the decision of the lower court. Justice Antonin Scalia, Clarence Thomas and Samuel Alito joined in the dissent. The majority opinion was written by Roberts and included the following statement: "Congress passed the Affordable Care Act to improve health insurance markets, not to destroy them."

2.What the decision means: Subsidies will be available to any person who buys health insurance on an exchange, whether it is run by a state or the federal government. The decision applies to over 6 million Americans who live in states without exchanges who purchase  insurance from the federal exchange.

3. An entertaining dissent: Scalia wrote a dissent peppered with zingers that have quickly been picked up on social media. His memorable lines include, "We should start calling this law SCOTUScare" and a reference to "interpretive jiggery-pokery." Scalia called the majority's reasoning "pure applesauce."

4. Majority opinion criticizes the law: "The Affordable Care Act contains more than a few examples of inartful drafting," noting that the law was sloppily written and contains duplicate sections.

5. Republican reaction: Republican presidential candidates were quick to sound off about the Supreme Court's decision. Rick Perry and Marc Rubio took to Twitter to blast the health care law.

6. Democrat reaction: High-profile Democrats also reacted to the Supreme Court's health care decision.
