The fact that there is a robust debate in Congress is good. The fact that the debate sometimes seems unanchored to facts is not so good.

I don't believe people should to be able to own guns.

Four years ago, I promised to end the war in Iraq. We did. I promised to refocus on the terrorists who actually attacked us on 9/11. We have. We've blunted the Taliban's momentum in Afghanistan, and in 2014, our longest war will be over. A new tower rises above the New York skyline, al Qaeda is on the path to defeat, and Osama bin Laden is dead.

Physically, I feel probably as good as I've ever felt. And I've got as much energy as I ever did. But what you feel after eight years - and I think you'd feel this no matter what, but anytime you have a big transition, it gets magnified - is time passes.

Based on current surveys of public opinion in the United States, it turns out that the majority of Americans think I've done a pretty good job.

In fact, the best thing we could do on taxes for all Americans is to simplify the individual tax code. This will be a tough job, but members of both parties have expressed an interest in doing this, and I am prepared to join them.

The absence of hope can rot a society from within.
