Back in the '50s and '60s, most politicians were concerned about not talking about faith, partly because there were consequences you had to deal with - (for instance) Catholicism had been made an issue.

One of the thing about being President - that can't be taught, you have to experience, is - there is the sheer weight of decision making. And when I make a decision to send 17,000 young Americans to Afghanistan - you can understand that intellectually. But understanding what that means for those families, for those young people - when you end up sitting at your desk, signing - a condolence letter to one of the family members of a fallen hero - you're reminded each and every day, at every moment, that - the decisions you make count.

That sort of lack of awareness on the part of an activist about the constraints of our political system and the constraints on this office, I think, sometimes would leave me to mutter under my breath. Very rarely did I lose it publicly. Yeah, usually I'd just smile.

You bomb ISIL. You're not trying to bomb innocent people. And that requires intelligence and confidence in our military to be able to develop the kinds of targets that we need. We're already doing Special Forces, who are going to help us gather that intelligence and help advise and assist and train local forces so that they can go after ISIL in areas like Raqqah and Mosul.

Clearly, Iran has influence in Iraq. Iraq has a majority Shi'a population, they have relationships to Iran. Some are natural.

[The Democrats] have got to do a better job of showing up.
