I actually think the only way that you can beat Trump is recognizing that he is a one- man wrecking machine fueled by this cult personality. So you have to attack him on those bases. None of these ideological positioning issues matter for [Donald] Trump.

I understand what a normal political speech is. You get up there, tell a few jokes, you have the flags behind you, and you speak for 10 or 15 minutes in broad generalities.

The next time you do a filibuster, keep walking around.

I think everybody is in agreement that America is a great entrepreneurial nation. We have got to encourage that. Of course, we have to support small and medium-sized businesses. But you can have all of the growth that you want and it doesn't mean anything if all of the new income and wealth is going to the top 1 percent.

I was not a great student at the University of Chicago. I think that is - the record will bare me out. But I spent a lot of time reading history, sociology, psychology - reading everything except what I was supposed to read for class the next day.

I believe what I call common sense gun reform. Plus, a revolution in mental health, making sure that if people are having a nervous breakdown, or are suicidal, or homicidal, they get the care they need when they need it. I think the vast majority of the American people can support and agenda composed of those features.

What I do know is that drones are a modern weapon. When used effectively, when taking out ISIS or terrorist leaders, that's pretty impressive. When bombing wedding parties of innocent people and killing dozens of them, that is, needless to say, not effective and enormously counterproductive. So whatever the mechanism, whoever is in control of that policy, it has to be refined so that we are killing the people we want to kill and not innocent collateral damage.
