Flipping through my colleagues' contributions to this series, it seems I'm not the only person having trouble choosing just one piece. We've been blessed with an abundance of talented writers and important stories to tell, and I could certainly point you toward plenty of great work, like Ann Friedman on Sarah Palin or Gabe Arana's prescient coverage of the legal challenge to Proposition 8. However, forced to choose, my favorite stories in the Prospect this year are from Adam Serwer's ongoing coverage of the clash of national security and civil liberties in the age of Obama.
