A very good friend of mine spent a fair amount of time doing postmortems and met with a number of the senior folks on the Romney campaign and they spent, what was it, $140, $160 million on data. And this friend of mine, who is a very sharp thinker, asked a series of questions, but the most important one he asked, he said, "What decisions did you make differently because of the data?" And he's coming from the private equity world where he wants to know, OK, and the answer from virtually every single senior Romney person was "nothing."

I will happily support anything that protects life.

I am long term optimistic and short term pessimistic on immigration. Long term, I'm optimistic because there's a lotta bipartisan agreement outside of Washington on immigration. There's overwhelming bipartisan agreement, number one, that we need to secure the borders. That we need to finally do something to stop illegal immigration.

We see a missile here, a bomb there - looks good on CNN. This is nonsense. This is not a strategy of a serious commander in chief.

Congress needs to send a strong signal that direct communication with the leader of the free world is a privilege, particularly for a regime that has been as hostile as Iran has been towards America for more than three decades. President Rouhani needs to take these two simple steps to demonstrate good faith before any further discussions.

I believe over the long term he's going to have the money, and he's got the message, that this is going to be one of the finalists for the presidential campaign.

As president, I wouldn't be making the day-to-day combat decisions. The job of the commander-in-chief is to lay the objective out and then you rely upon the generals and admirals and commanders to give you their expert advice on the tools needed to carry out that objective.
