Decision-making power, whether it's on foreign affairs or domestic affairs, is concentrated in the White House in a reasonably small circle.

Palin is smart, politically skilled, courageous and likable. Her convention and debate performances were impressive.

I think Romney's foreign policy is sensible.

I think the Barack Obama position and the majority position of American Jews and a lot of Americans is a two-state solution between Israel and Palestine. Settlements get in the way of that. If they're not stopped soon, there is no prospect for that type of solution.

I'm not sure [Donald] Trump has had that distinction between private and public life in his head. And so, I think there's likely to be an erosion of just that standard, that different standard, consciousness, and I think it's likely we'll see what we haven't seen in the last eight years and even the last 12 or 16 of private enrichment in office and scandals where people have to resign and things like that, because just once the standards go, behavior tends to go.

I wouldn't say philosophy and theology are dead. Brain science doesn't invent new philosophies but it helps remind us which of our existing philosophies are more true.

If Donald Trump wants to fire somebody for not getting Obamacare repealed, he should fire himself.
