America is an idea, but it's an idea that brings with it some baggage, like power brings responsibility. It's an idea that brings with it equality, but equality even though it's the highest calling, is the hardest to reach. The idea that anything is possible, that's one of the reasons why I'm a fan of America. It's like hey, look there's the moon up there, let's take a walk on it, bring back a piece of it. That's the kind of America that I'm a fan of.
