On healthcare we are the prisoner of our past. The way we got to develop any kind of medical insurance program was during World War II when companies facing shortages of workers began to offer healthcare benefits as an inducement for employment.

And after the war when soldiers came back and went back into the market there was a lot of competition, because the economy was so heated up.

I think it's important that we do it [defeat ISIS] in concert with other nations in Europe, the Middle East, elsewhere if necessary. And that means you've got to work with people. You don't insult them. You don't insult their religion. And it means we have to see our entire country, all of the people in it, as part of our first line of defense.

I do think questions have been raised and questions have to be answered.And there is no way to predict what comes in the door of that White House from day to day that can pose a threat to the United States or one of our friends and allies, and I think this is a big part of the job interview that we are all conducting with the voters here.
