[Michelle Obama] used to say to our friends, "Barack's exactly the kind of guy I want to be president. I just wish he didn't want to do it when I was married to him."

My guiding principle as president has been to try to do the right thing even when it's not politically convenient.

You can choose a future where more Americans have the chance to gain the skills they need to compete, no matter how old they are or how much money they have.

Government without a tough and vibrant media is not an option for the United States of America.
