My particular worries on any given day - how I'm doing in the polls or what somebody is saying about me... for good or for ill - isn't particularly relevant. What is relevant is: What am I building that lasts?

I believe that the free enterprise system is the greatest engine of prosperity the world's ever known.

My view is that discrimination against anyone at the ballot box is wrong and should have the full enforcement of the federal government.

Families across America are feeling the pinch as they watch debts mount, bills pile up and savings disappear.

I continue to believe when I said in Hanover, that the E.U. remains one of the world's great political and economic achievements, and that those achievements should not be taken for granted.

And if we walk away now, if we simply retreat into our respective corners, we will never be able to come together and solve challenges like health care, or education, or the need to find good jobs for every American.

We must build a world free of unnecessary barriers, stereotypes, and discrimination. ... policies must be developed, attitudes must be shaped, and buildings and organizations must be designed to ensure that everyone has a chance to get the education they need and live independently as full citizens in their communities.
