It is possible to work across the aisle in Washington, but it's hard. And I think it's been made worse by the kind of 24-hour news cycle, the fact that everything is on TV before you can work things out quietly. I think it's the intensity of information that makes it feel more difficult to get things done. But I didn't leave with a bitter taste about the politics. The one thing that I would say is, I do think there is an unfortunate tendency to turn political differences, or policy differences, into critiques of one another's character or motives, and that's unfortunate.

I think there's sometimes too much attention to a few people who do hold extreme views. Most Americans go about their lives living in communities that are increasingly multiethnic, increasingly multi-religious. And they are welcoming of people who are not like themselves.
