Our planet is changing in ways that will have profound impacts on all of humankind.

Now, as a nation, we don't promise equal outcomes, but we were founded on the idea everybody should have an equal opportunity to succeed. No matter who you are, what you look like, where you come from, you can make it. That's an essential promise of America. Where you start should not determine where you end up.

For me, Lincoln is like just a handful of people - a Gandhi, or a Picasso, or a Martin Luther King Jr. - who is an original and captures something essential.

But while they're adding teachers in places like South Korea, we're laying them off in droves. It's unfair to our kids. It undermines their future and ours. And it has to stop. Pass this bill, and put our teachers back in the classroom where they belong.

We were just at the beginnings of a recovery [in 2010]. And the, you know, whoever is president at that point is gonna get hit and his party's gonna get hit. That then means that suddenly you've got a redistricting in which a lot of state legislatures are now Republican. They draw lines that give a huge structural advantage in subsequent elections.

Our hearts are broken today for the parents and grandparents, sisters and brothers of these children and the families of the adults we lost....May god bless the memory of the victims and in the words of scripture heal the broken hearted and bind up their wounds.

I believe in term limits for presidents because I think that there is no doubt I'm a better president now than I was when I start. I would argue that I am the best president I've ever been over the last year or two. My team is more effective than it's ever been.But what is also true is that number one, this is grueling.
