I work really long hours and work a lot and have done press tours and junkets, but there is nothing like a presidential campaign that I have experienced before...I think at one point we visited three different cities in one state in 12 hours. It's exhausting.
The state of the world, of course, is constantly changing, and so is theory.
How do I know why Miles walks off the stage? Why don't you ask him? And besides, maybe we'd all like to be like Miles, and just haven't got the guts.
