Crime can be a unifying argument - not an argument that people use as a code for us vs. them.

Republicans always try to paint Democrats as weak on defense. This time, they can't. After all, Mitt Romney's idea of an overseas accomplishment is sending U.S. jobs there.

I think teaching should be an exalted profession, not a picked-on profession.

In education, I'm going to try to find what works. One thing I want to do is improve the quality of teachers. There are a lot of people who want to go into teaching; it's fundamentally a very fulfilling profession. But people don't feel they have financial support. We pay starting teachers in particular too little to attract the quality people that we need. I want to make it easier for good people who want to go into teaching to do that.

There are many reasons why Mitt Romney should not become president, but perhaps the most important of all is the narrowness of his experience, perspective and vision.

I think there's going to be a lot of Americans who are really willing to be much more active than they were before, because they're worried about where Trump is headed.

The Democratic Party was always there on crime, but in the past we let the ideologues on the left dominate. The Republicans may still let the ideologues on the right dominate.
