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.
