Experience is not the only point, judgment is. And once again, back in 2002, when we both [with Hillary Clinton] looked at the same evidence about the wisdom of the war in Iraq, one of us voted the right way and one of us didn't.

The focus, to my mind, is to make sure that Donald Trump does not become president of the United States. I think by temperament he is unqualified to be president. I think his views - you have a guy who's running for president who rejects science, doesn't even believe climate change is real, let alone wants to do something about it, wants to give hundreds of billions of dollars in tax breaks to the top two-tenths of one percent.

I don't run against Hillary Clinton. I run on the most important issues facing America.

The middle class in America is at a tipping point. It will not last another generation if we don't boldly change course now.

I took an oath to support and defend the Constitution of the United States, and I'm concerned that voting for this [anti-terrorism] legislation fundamentally violates that oath.

I want to say something, and it may sound harsh, not to you, but to the American people. In a sense, in my view, the business model of Wall Street is fraud. It's fraud. I believe that corruption is rampant, and the fact that major bank after major bank has reached multi billion dollar settlements with the United States government when we have a weak regulator system tells me that not only did we have to bail them out once, if we don't start breaking them up, we're going to have to bail them out again, and I do not want to see that happen.

Politics is not about a person. We transform America not by electing some guy or woman to be president; we transform this country when millions of people stand up and fight back. That will result in good leadership on top. So the goal right now is not to worry about who's going to be running in 2020 or 2080. The goal now is to mobilize millions of people around a progressive agenda.
