There's a utility in the democracy refreshing itself on an ongoing basis.

Perfect is unattainable. Better is possible.

Environmentalism is not an upper-income issue, it's not a white issue, it's not a black issue, it's not a South or a North or an East or a West issue. It's an issue that all of us have a stake in. And if I can do anything to make sure that not just my daughter but every child in America has green pastures to run in and clean air to breathe and clean water to swim in, then that is something I'm going to work my hardest to make happen.

I'm willing to work with anyone of either party who has a good idea and the commitment to see through. And we should all expect you to hold us accountable for our progress or our failure to deliver.

I will call not just on Israel, but on the Palestinians, on the Arab States, and the international community to join us in this effort, because the burden of making hard choices must not be Israel’s alone.

I think [ unpopular presidential candidates ] indicates, at least on the Democratic side, that we've got more work to do to strengthen our grassroots networks.

We cannot tolerate a nuclear Iran. It would be a game changer. Not only would it threaten Israel, a country that is our stalwart ally, but it would also create an environment in which you could set off an arms race in this Middle East.
