You cannot lead America to a positive tomorrow with revenge on one's mind. Revenge is so incredibly negative.

I think by not participating in the current political debate, hopefully I'm sending a signal that will help set a tone.

I regret that we weren't able to reform Social Security. The fact that we weren't able to when we had majorities in the House and the Senate I think reflected poorly on our political party.

No one wants to be a polarizer, but on the other hand, if you think you're doing right and you believe the decisions you make will lead to a better tomorrow, then they're worthy of defense.

I've got a great sense of where I want to lead and I'm comfortable with why I'm running. And, you know, the call on that speech was, beware. This is going to be a tough campaign.

Now, there are some who would like to rewrite history - revisionist historians is what I like to call them.

I've directed the full resources of our intelligence and law enforcement communities to find those responsible and bring them to justice. We will make no distinction between the terrorists who committed these acts and those who harbor them.
