It can be here today and gone tomorrow.

I think we identify ourselves by labels or things that we are able to do: I am this. I am a good cook. I am a good mother. I am a good this. I am a good doctor. I am a good lawyer. When you can’t do those things anymore, you wonder where your identity is.

You know, I think my biggest concern [if Mitt is elected], obviously, would just be for his mental well-being. I have all the confidence in the world in his ability, in his decisiveness and his leadership skills, in his understanding of the economy, in his understanding of what's missing right now in the economy - you know, pieces that are missing to get this jump-started. So for me I think it would just be the emotional part of it.

It's the moms of this nation - single, married, widowed - who really hold this country together. We're the mothers, we're the wives, we're the grandmothers, we're the big sisters, we're the little sisters, we're the daughters. You know it's true, don't you? You're the ones who always have to do a little more.

Another son came along 18 months later, although we waited four years to have the third, because Mitt was still in school and we had no income except the stock we were chipping away at. We were living on the edge, not entertaining. No, I did not work. Mitt thought it was important for me to stay home with the children, and I was delighted.

I know what it's like to struggle and to have those concerns that all mothers have.

We need to respect choices that women make.
