"Four years ago, I stood before you and told you my story -- of the brief union between a young man from Kenya and a young woman from Kansas who weren't well-off or well-known but shared a belief that in America, their son could achieve whatever he put his mind to.
"It is that promise that has always set this country apart -- that through hard work and sacrifice, each of us can pursue our individual dreams but still come together as one American family, to ensure that the next generation can pursue their dreams as well.
"It is why I stand here tonight. Because for 232 years, at each moment when that promise was in jeopardy, ordinary men and women -- students and soldiers, farmers and teachers, nurses and janitors -- found the courage to keep it alive.
"We meet at one of those defining moments -- a moment when our nation is at war, our economy is in turmoil, and the American promise has been threatened once more."
"These challenges are not all of government's making. But the failure to respond is a direct result of a broken politics in Washington and the failed policies of George W. Bush.
"America, we are better than these last eight years. We are a better country than this."
"This moment -- this election -- is our chance to keep, in the 21st century, the American promise alive. Because next week, in Minnesota, the same party that brought you two terms of George Bush and Dick Cheney will ask this country for a third. And we are here because we love this country too much to let the next four years look just like the last eight. On Nov. 4, we must stand up and say: 'Eight is enough.'
"Now let there be no doubt. The Republican nominee, John McCain, has worn the uniform of our country with bravery and distinction, and for that we owe him our gratitude and respect. And next week, we'll also hear about those occasions when he's broken with his party as evidence that he can deliver the change that we need.
"But the record's clear: John McCain has voted with George Bush 90% of the time. Sen. McCain likes to talk about judgment, but really, what does it say about your judgment when you think George Bush has been right more than 90% of the time? I don't know about you, but I'm not ready to take a 10% chance on change."
"So let me spell out exactly what that change would mean if I am president. . . .
"Change means a tax code that doesn't reward the lobbyists who wrote it but the American workers and small businesses who deserve it.
"Unlike John McCain, I will stop giving tax breaks to companies that ship our jobs overseas and I will start giving them to companies that create good jobs right here in America.
"I will eliminate capital gains taxes for the small businesses and the start-ups that will create the high-wage, high-tech jobs of tomorrow.
"I will cut taxes -- cut taxes -- for 95% of all working families. Because in an economy like this, the last thing we should do is raise taxes on the middle class.
"And for the sake of our economy, our security and the future of our planet, I will set a clear goal as president: In 10 years, we will finally end our dependence on oil from the Middle East. We will do this."
"Now is the time to finally meet our moral obligation to provide every child a world-class education, because it will take nothing less to compete in the global economy. Michelle and I are only here tonight because we were given a chance at an education. And I will not settle for an America where some kids don't have that chance. . . .
"Now is the time to finally keep the promise of affordable, accessible healthcare for every single American. If you have healthcare, my plan will lower your premiums. If you don't, you'll be able to get the same kind of coverage that members of Congress give themselves. And as someone who watched my mother argue with insurance companies while she lay in bed dying of cancer, I will make certain those companies stop discriminating against those who are sick and need care the most."
"If John McCain wants to have a debate about who has the temperament, and judgment, to serve as the next commander in chief, that's a debate I'm ready to have.
"For while Sen. McCain was turning his sights to Iraq just days after 9/11, I stood up and opposed this war, knowing that it would distract us from the real threats that we face. When John McCain said we could just 'muddle through' in Afghanistan, I argued for more resources and more troops to finish the fight against the terrorists who actually attacked us on 9/11, and made clear that we must take out Osama bin Laden and his lieutenants if we have them in our sights.
"John McCain likes to say that he'll follow Bin Laden to the gates of hell -- but he won't even follow him to the cave where he lives.
