I was very close to my mother, and her death, which left a gaping hole in my life, has been very difficult for me and my father in a lot of ways.

But one of the things I learned is that when you fight for something you believe in and you tell the truth and you do your best, you can always hold your head up high and no one can take that away from you.

I just learned not to take a single thing for granted, and I think it just is extraordinary.

You're blinded by lights and you see all these people who come out, and it's exciting. It's scary and it's exciting all rolled into one.

I think that standing onstage on January 19th, and my father had just defied all expectations and won Iowa, was by far the most surreal moment.

We don't necessarily always agree, but hopefully we make each other think, and that's what matters.

The dinner table is a lively debate, and everybody weighs in in a different way. I like that, though.
