We cannot let this moment slip away. We have come too far and accomplished too much.
Now, the journey ahead will not be easy. Some will say we can't do it, that it's too hard, we're just not up to the task. But for as long as America has existed, it has been the American way to reject can't-do claims and to choose instead to stretch the boundaries of the possible through hard work, determination, and a pioneering spirit.
It is this belief, this optimism that Senator Obama and I share and that has inspired so many millions of our supporters to make their voices heard. So today I am standing with Senator Obama to say: Yes, we can!
