So [Vladimir] Putin is a mess. He's committed all sort of murderous thuggery, and I am opposed to the way Putin conducts himself in world affairs, and I hope that the president also wants to show moral leadership about this issue.

Let's be clear: Has the U.S. ever made any mistakes? Of course.Is the U.S. at all like [Vladimir] Putin's regime? Not at all.

People think if they voted for somebody, they should reflexively defend everything they do or say. And if you voted against somebody, you should just as reflexively oppose everything they do or say. It's not very helpful. What's more constructive for our kids is to go on a case-by-case basis, evaluating particular policies.

[Vladimir] Putin is an enemy of political dissent. The U.S. celebrates political dissent and the right for people to argue free from violence about places where our ideas are in conflict.

The U.S. affirms freedom of speech.[Vladimir] Putin is no friend of freedom of speech.

I think the category of perpetual adolescence, it's a new thing, and it's a dangerous thing. Adolescence is a pretty glorious concept. It's about intentionally transitioning from childhood to adulthood. Being stuck in adolescence - that's a hell. Peter Pan is a dystopia, and we forget that.

The real number of the US' obligations, unfunded obligations that we're passing on to our future generates is more like $70 trillion to $75 trillion.

But fundamentally, health entitlements are the thing that will bankrupt our kids. We need to fix that for the long-term.
