He's going to speak at about 8:30 pm ET tonight. Here are some more excerpts:


Senator Clinton has earned great respect for her tenacity and courage. The media often overlooked how compassionately she spoke to the concerns and dreams of millions of Americans, and she deserves a lot more appreciation than she sometimes received. As the father of three daughters, I owe her a debt for inspiring millions of women to believe there is no opportunity in this great country beyond their reach. I am proud to call her my friend.


Admits it's a change election


The decision facing Americans in this election couldn’t be more important to the future security and prosperity of American families. This is, indeed, a change election. No matter who wins this election, the direction of this country is going to change dramatically. But, the choice is between the right change and the wrong change; between going forward and going backward.


Where McCain = Forward


The right change recognizes that many of the policies and institutions of our government have failed. They have failed to keep up with the challenges of our time because many of these policies were designed for the problems and opportunities of the mid to late 20th Century, before the end of the Cold War; before the revolution in information technology and rise of the global economy. The right kind of change will initiate widespread and innovative reforms in almost every area of government policy -- health care, energy, the environment, the tax code, our public schools, our transportation system, disaster relief, government spending and regulation, diplomacy, the military and intelligence services. Serious and far-reaching reforms are needed in so many areas of government to meet our own challenges in our own time.


Pre-butting McCain/Bush


You will hear from my opponent’s campaign in every speech, every interview, every press release that I’m running for President Bush’s third term. You will hear every policy of the

President described as the Bush-McCain policy. Why does Senator Obama believe it’s so important to repeat that idea over and over again? Because he knows it’s very difficult to get Americans to believe something they know is false. So he tries to drum it into your minds by constantly repeating it rather than debate honestly the very different directions he and I would take the country. But the American people didn’t get to know me yesterday, as they are just getting to know Senator Obama. They know I have a long record of bipartisan problem solving. They’ve seen me put our country before any President -- before any party -- before any special interest -- before my own interest. They might think me an imperfect servant of our country, which I surely am. But I am her servant first, last and always.

The distancing


I disagreed strongly with the Bush administration’s mismanagement of the war in Iraq. I called for the change in strategy that is now, at last, succeeding where the previous strategy had failed miserably. I was criticized for doing so by Republicans. I was criticized by Democrats. I was criticized by the press. But I don’t answer to them. I answer to you. And I would be ashamed to admit I knew what had to be done in Iraq to spare us from a defeat that would endanger us for years, but I kept quiet because it was too politically hard for me to do. No ambition is more important to me than the security of the country I have defended all my adult life.
