It is natural to try to understand one's own time and to seek to analyse the forces that move it.
One of the things I thought a lot about was how can we get the views, for instance, the main plaza, you look up to Telegraph Hill from there and therefore it would be a disaster to close that view off.
And you know what? At the end of the day, it gets down to Obama and Romney. And what it's going to get down to is this. Obama is going to say, 'I inherited a mess and I'm making it better.' And Romney is going to say, 'you haven't made it good enough. And I can do far better than you have done.'
