Our government shouldn’t make promises we cannot keep — but we must keep the promises we’ve already made. - Barack Obama

Africa’s progress will also depend on security and peace -- because an essential part of human dignity is being safe and free from fear.

I don’t pretend to have all the answers. And I’m not going to offer some grand theory – not when it’s a beautiful day and you’ve got some celebrating to do. I’m not going to get partisan, either, because that’s not what citizenship is about. In fact, I am asking the same thing of you that President Bush did when he spoke at this commencement in 2002: “America needs more than taxpayers, spectators, and occasional voters,” he said. “America needs full-time citizens.” And as graduates from a university whose motto is “Education for Citizenship,” that’s what your country expects of you. So briefly, I will ask you for two things: to participate, and to persevere. After all, your democracy does not function without your active participation. At a bare minimum, that means voting, eagerly and often. It means knowing who’s been elected to make decisions on your behalf, what they believe in, and whether or not they deliver. If they don’t represent you the way you want, or conduct themselves the way you expect – if they put special interests above your own – you’ve got to let them know that’s not okay. And if they let you down, there’s a built-in day in November where you can really let them know that’s not okay.
