Our children will always remember that there was someone who felt our struggle and made a long journey to protect innocent people." That is the difference we make in the world.

I have no more campaigns to run... I know because I won both of them.

If you work hard. And are responsible. You should be rewarded.

I have fought against spending. I have fought against special interests. I have fought for reform.

What I consistently say to young people - I say it in the United States, but I'll say it here in Germany and across Europe: Do not take for granted our systems of government and our way of life. I think there is a tendency, because we have lived in an era that has been largely stable and peaceful, at least in advanced countries, where living standards have generally gone up, there is a tendency I think to assume that that's always the case.
