Over the weekend, Maldives held its first cabinet meeting underwater. Yes, underwater: The ministers of the tiny island nation all put on scuba gear and sat at desks six meters below sea-level in a rather brazen bid to get people to pay attention to the rising sea levels that are threatening countries like the Maldives.

It's been a long year--Barack Obama has faced, in rough order, John McCain, global financial collapse, Mahmoud Ahmadinejad, the Blue Dogs, the Progressive Caucus, the Gang of Six, Glenn Beck, Representative Joe Wilson (R-Hissy), and the third of Republicans convinced he was born somewhere else. Of course, minus the birth certificates, roughly the same has been true for Hu Jintao and Nicolas Sarkozy, for Angela Merkel and Manmohan Singh. That's what politics is--a series of challenges, which are rarely won or lost completely. You get part of what you wanted (everyone with health insurance), and maybe you leave other stuff for another day (the public option). That's why we call politics the pursuit of the possible.
