E.U. need to be nurtured and cultivated and protected and fought for because the achievements that we've seen on this continent, in contrast to a divided Europe of the previous century, are ones that remind us of how important it is that we work together.

What I'm thinking about are the millions of people, many of whom write me very personal letters :"Dear Mr. President: I did not vote for you. I was against Obamacare. And then my son who didn't have health insurance signed up and we just found out that he had an illness. And thankfully he's now covered, otherwise he might not have gotten treatment and I might have lost my house."

We should foster a culture in which people's private religious beliefs, including atheists and agnostics, are respected. And that's the kind of culture that I think allows all of us, then, to believe what we want. That's freedom of conscience. That's what our Constitution guarantees.

Increasing America’s debt weakens us domestically and internationally. Leadership means that 'the buck stops here.' Instead, Washington is shifting the burden of bad choices today onto the backs of our children and grandchildren. America has a debt problem and a failure of leadership.

Here's the truth: even if countries like the United States curb our emissions, if growing countries like India - with soaring energy needs - don't also embrace cleaner fuels, then we don't stand a chance against climate change.
