I think it's fair to say that my temperament is steady - and on the buoyant side.

Now, today, some children are enrolled in excellent programs. Some children are enrolled in mediocre programs. And some are wasting away their most formative years in bad programs....That's why I'm issuing a challenge to our states: Develop a cutting-edge plan to raise the quality of your early learning programs; show us how you'll work to ensure that children are better prepared for success by the time they enter kindergarten. If you do, we will support you with an Early Learning Challenge Grant that I call on Congress to enact.

Political gerrymandering makes the incentive for most members of Congress to play to the extremes of their base rather than to the center.

It's a generational project just to get America to live up fully to its ideals and to have the kind of society where everybody has a shot, and every kid is getting a good education, and people are getting living wages, and they have decent retirement.

My little girls can break my heart. They can make me cry just looking at them eating their string beans.

This massacre in Orlando is therefore a further reminder of how easy it is for someone to get their hands on a weapon that lets them shoot people in a school or in a house of worship or a movie theater or in a nightclub. And we have to decide if that's the kind of country we want to be. And to actively do nothing is a decision, as well.

There are a lot of very religious scientists around. I think the problem here is that in our school systems, and to some degree - and this is where it is relevant - with school boards around the country that are mandating curriculums and textbooks, you start seeing this weird watering down of scientific fact so that our kids are growing up in an environment - and this connects to what I was saying earlier abou the media - where everything's contested. Where nothing is true.
