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.
