Citizenship means standing up for the lives that gun violence steals from us each day. I have seen the courage of parents, students, pastors, and police officers all over this country who say 'we are not afraid,' and I intend to keep trying, with or without Congress, to help stop more tragedies from visiting innocent Americans in our movie theaters, shopping malls, or schools like Sandy Hook.

We may never understand what leads anybody to terrorize their fellow human beings. Such violence, such evil is senseless. It's beyond reason.

I think the American people recognize is after a decade of war it's time to do some nation building here at home. And what we can now do is free up some resources, to, for example, put Americans back to work, especially our veterans, rebuilding our roads, our bridges, our schools, making sure that, you know, our veterans are getting the care that they need when it comes to post-traumatic stress disorder and traumatic brain injury, making sure that the certifications that they need for good jobs of the future are in place.

The path towards sustainable energy sources will be long and sometimes difficult. But America cannot resist this transition, we must lead it.

That's what the leadership was teaching me, day by day: that the self-interest I was supposed to be looking for extended well beyond the immediacy of issues, that beneath the small talk and sketchy biographies and received opinions, people carried with them some central explanation of themselves. Stories full of terror and wonder, studded with events that still haunted or inspired them. Sacred stories.

At least Romney and McCain, they respect the rule of law. At least Romney and McCain, they understand their limitations.
