As a nuclear power - as the only nuclear power to have used a nuclear weapon - the United States has a moral responsibility to act.

Tonight, we gather to affirm the greatness of our nation - not because of the height of our skyscrapers, or the power of our military, or the size of our economy. Our pride is based on a very simple premise, summed up in a declaration made over two hundred years ago.

Here at this site, Solyndra expects to make enough solar panels each year to generate 500 megawatts of electricity. And over the lifetime of this expanded facility, that could be like replacing as many as eight coal-fired power plants.

And we can see the positive impacts right here at Solyndra. Less than a year ago, we were standing on what was an empty lot.But through the Recovery Act, this company received a loan to expand its operations. This new factory is the result of those loans.

Part of the reason that our politics seems so tough right now and facts and science and argument does not seem to be winning the day all the time is because we're hardwired not to always think clearly when we're scared. And the country's scared.

There is probably a perverse pride in my administration... that we were going to do the right thing, even if short-term it was unpopular. And I think anybody who's occupied this office has to remember that success is determined by an intersection in policy and politics and that you can't be neglecting of marketing and P.R. and public opinion.

When we think of the major threats to our national security, the first to come to mind are nuclear proliferation, rogue states and global terrorism. But another kind of threat lurks beyond our shores, one from nature, not humans - an avian flu pandemic.

I know that campaigns can seem small, and even silly. Trivial things become big distractions. Serious issues become sound bites. And the truth gets buried under an avalanche of money and advertising. If you're sick of hearing me approve this message, believe me - so am I.

I mean, I do think at a certain point you've made enough money.

Money is not the only answer, but it makes a difference.

We need earmark reform, and when I'm President, I will go line by line to make sure that we are not spending money unwisely.

We need somebody who's got the heart, the empathy, to recognize what it's like to be a young teenage mom, the empathy to understand what it's like to be poor or African-American or gay or disabled or old - and that's the criterion by which I'll be selecting my judges.

I don't think marriage is a civil right, but I think that being able to transfer property is a civil right.

I think there are a whole host of things that are civil rights, and then there are other things - such as traditional marriage - that, I think, express a community's concern and regard for a particular institution.

What I believe is that marriage is between a man and a woman, but what I also believe is that we have an obligation to make sure that gays and lesbians have the rights of citizenship that afford them visitations to hospitals, that allow them to be, to transfer property between partners, to make certain that they're not discriminated on the job.

I opposed the Defense of Marriage Act in 1996. It should be repealed and I will vote for its repeal on the Senate floor. I will also oppose any proposal to amend the U.S. Constitution to ban gays and lesbians from marrying.

I believe marriage is between a man and a woman. I am not in favor of gay marriage. But when you start playing around with constitutions, just to prohibit somebody who cares about another person, it just seems to me that's not what America's about. Usually, our constitutions expand liberties, they don't contract them.

Focusing your life solely on making a buck shows a certain poverty of ambition. It asks too little of yourself. Because it's only when you hitch your wagon to something larger than yourself that you realize your true potential.

We can't drive our SUVs and eat as much as we want and keep our homes on 72 degrees at all times... and then just expect that other countries are going to say OK. That's not leadership. That's not going to happen.

Where the stakes are the highest, in the war on terror, we cannot possibly succeed without extraordinary international cooperation. Effective international police actions require the highest degree of intelligence sharing, planning and collaborative enforcement.
