The Patient Protection and Affordable Care Act, often shortened to the Affordable Care Act (ACA) or nicknamed Obamacare, is a United States federal statute enacted by the 111th United States Congress and signed into law by President Barack Obama on March 23, 2010. The term "Obamacare" was first used by opponents, then reappropriated by supporters, and eventually used by President Obama himself.
President Barack Obama made two successful appointments to the Supreme Court of the United States. The first was Judge Sonia Sotomayor to fill the vacancy created by the retirement of Justice David H. Souter. The second appointment was that of Solicitor General Elena Kagan to replace the retired John Paul Stevens.
Numerous candidates entered the Democratic Party presidential primaries, but the field quickly narrowed to a duel between Obama and Senator Hillary Clinton, with the race remaining close throughout the primary process. On June 7, 2008, Clinton ended her campaign and endorsed Obama.
