Whatever the outcome in November, Sen. Obama has achieved a great thing, for himself and for his country.... Don’t tell him I said this, but he is an impressive fellow in many ways.

We have many advantages in the fight against global warming, but time is not one of them. Instead of idly debating the precise extent of global warming, or the precise timeline of global warming, we need to deal with the central facts of rising temperatures, rising waters, and all the endless troubles that global warming will bring. We stand warned by serious and credible scientists across the world that time is short and the dangers are great. The most relevant question now is whether our own government is equal to the challenge.

At its core, the economy isn't the sum of an array of bewildering statistics. It's about where Americans work, how they live, how they pay their bills today and save for tomorrow. It's about small businesses opening their doors, hiring employees and growing. It's about giving workers the education and training to find a good job and prosper in it. It's about the aspirations of the American people to build a better life for their families; dreams that begin with a job.

The issue of economics is something that I've really never understood as well as I should.

We must also get government's fiscal house in order. American workers and families pay their bills and balance their budgets, and I will demand the same of the government. A government that spends wisely and balances its budget is a catalyst for economic growth and the creation of good and secure jobs.

Whoever controls oil controls much more than oil.

America has seen tough times before. We've always known how to get through them. And we've always believed our best days are ahead of us. I believe that still. But we must rise to the occasion, as we always have; change what must be changed; and make the future better than the past.

I'm going to be honest: I know a lot less about economics than I do about military and foreign policy issues. I still need to be educated.

Do not yield. Do not flinch. Stand up. Stand up with our President and fight. We're Americans. We're Americans, and we'll never surrender. They will.

The hectic but repetitive routine of presidential campaigns often seems to consist entirely of back and forth charges between candidates, punctuated by photo ops, debates and the occasional policy speech, followed by another barrage of accusations and counter accusations, formulated into the soundbites preferred by cable news producers. It is a little hypocritical for candidates or reporters to criticize these deficiencies. They are our creation. Campaigns and the media collaborated as architects of the modern presidential campaign, and we deserve equal blame for the regret we feel from time to time over its less than inspirational features.

Many retired Americans face the terrible reality of deciding whether to buy food, pay rent or buy their prescriptions. And their government should help them. But when we added the prescription drug benefit to Medicare, a new and costly entitlement, we included many people who are more than capable of purchasing their own medicine without assistance from taxpayers who struggle to purchase their own. People like Bill Gates and Warren Buffet don't need their prescriptions underwritten by taxpayers. Those who can afford to buy their own prescription drugs should be expected to do so. This reform alone will save billions of dollars that could be returned to taxpayers or put to better use.

However just the cause, we should mourn for all that is lost when war claims its wages from us.

I believe in evolution. But I also believe, when I hike the Grand Canyon and see it at sunset, that the hand of God is there also.

For too long, now, Washington has been consumed by a hyper-partisanship that treats every serious challenge facing us as an opportunity to trade insults; disparage each other's motives; and fight about the next election. For all the problems we face, if you ask Americans what frustrates them most about Washington, they will tell you they don't think we're capable of serving the public interest before our personal and partisan ambitions; that we fight for ourselves and not for them. Americans are sick of it, and they have every right to be.

In our free society, it is left to each one of us to make our own way in the world -- and our jobs, businesses, savings, pensions, farms, and homes are the work of years. Take these away and you are diminishing a lot more than the GDP, or the final tally on the Big Board on Wall Street. Take these away, and a million dreams are undone.

There's never been a problem Americans couldn't solve. We are the world's leaders, and leaders don't fear change.

Never get into a wrestling match with a pig. You both get dirty, and the pig likes it.

We are not people who believe only in the survival of the fittest. Work in America is more than a paycheck; it a source of pride, self-reliance and identity.
