And you know what it's worked before. Because it feeds into the cynicism we all have about government. When Washington doesn't work, all its promises seem empty. If your hopes have been dashed again and again, then it's best to stop hoping, and settle for what you already know.

I get it. I realize that I am not the likeliest candidate for this office. I don't fit the typical pedigree, and I haven't spent my career in the halls of Washington.

But I stand before you tonight because all across America something is stirring. What the naysayers don't understand is that this election has never been about me. It's been about you.

For eighteen long months, you have stood up, one by one, and said enough to the politics of the past. You understand that in this election, the greatest risk we can take is to try the same old politics with the same old players and expect a different result. You have shown what history teaches us that at defining moments like this one, the change we need doesn't come from Washington. Change comes to Washington. Change happens because the American people demand it, because they rise up and insist on new ideas and new leadership, a new politics for a new time.

America, this is one of those moments.

I believe that as hard as it will be, the change we need is coming. Because I've seen it. Because I've lived it. I've seen it in Illinois, when we provided health care to more children and moved more families from welfare to work. I've seen it in Washington, when we worked across party lines to open up government and hold lobbyists more accountable, to give better care for our veterans and keep nuclear weapons out of terrorist hands.

And I've seen it in this campaign. In the young people who voted for the first time, and in those who got involved again after a very long time. In the Republicans who never thought they'd pick up a Democratic ballot, but did. I've seen it in the workers who would rather cut their hours back a day than see their friends lose their jobs, in the soldiers who re-enlist after losing a limb, in the good neighbors who take a stranger in when a hurricane strikes and the floodwaters rise.

This country of ours has more wealth than any nation, but that's not what makes us rich. We have the most powerful military on Earth, but that's not what makes us strong. Our universities and our culture are the envy of the world, but that's not what keeps the world coming to our shores.

Instead, it is that American spirit that American promise that pushes us forward even when the path is uncertain; that binds us together in spite of our differences; that makes us fix our eye not on what is seen, but what is unseen, that better place around the bend.
