[Donald Trump] doesn't deal well with criticism and blame and I don't think he could competently manage the office of the presidency given the criticism and challenge that you face every single day as the President of the United States.

We're getting to the point where we're impinging on democratic institutions in this country and I think, you know, it takes a certain - not a suspension of disbelief - but willingness to go along with other people to get the ship of state going forward. I'm not sure that happens in a [Donald] Trump presidency, frankly.

Opposing the free flow of goods or people is a bad idea.

I think government has a major role to play in helping us with the pursuit of happiness.

Do we believe that there is equal economic opportunity out there in the real world, right now, for each and every one of these groups? If we believed in the tooth fairy, if we believed in the Easter Bunny, we might well believe that.

I've been at some pains to say that I fear for the country if Mr.[DonALD] Trump should be elected. I think it's a candidacy without any parallel that I can recall.

Government can contribute to a shared sense of purpose on the part of the citizenry; that's its highest and best application.
