[George Bush] has raised taxes on the people driving pickup trucks and lowered taxes on the people riding in limousines. We can do better.

Promising too much can be as cruel as caring too little.

I think it's crazy for us to play games with our children's future. We know what's happening to the climate, we have a highly predictable set of consequences if we continue to pour greenhouse gases into the atmosphere.

This is one way that wealthy Americans could really contribute. They could put hundreds of millions of dollars into the infrastructure bank, be a good investment for them, for their children, for their grandchildren, and they would directly contribute to revitalizing a big sector of middle-class wages in America and making our country more productive, so that we could create more opportunity. But I think that we could get a lot of grassroots support from, like, local chambers of commerce and other things if they understood exactly how this infrastructure bank would work.

More than any other nation on Earth, America has constantly drawn strength and spirit from wave after wave of immigrants. In each generation, they have proved to be the most restless, the most adventurous, the most innovative, the most industrious of people. Bearing different memories, honoring different heritages, they have strengthened our economy, enriched our culture, renewed our promise of freedom and opportunity for all.

I believe that this country's policies should be heavily biased in favor of nondiscrimination.

I admire that about the Republicans: The evidence does not faze them. They are not bothered at all by the facts.
