I can think about what [Mahatma] Gandhi said or [Martin Luther] King said about violence begetting violence, and still be true to my job by asking myself the question whenever we're confronted with a situation where some may be arguing for military action: Will this actually result in America being safer, or the most lives being saved?

But having made my decision as Commander-in-Chief based on what I am convinced is our national security interests, I will seek authorization for the use of force from the American people's representatives in Congress.

I think raising wages, investing in infrastructure, making sure that people have access to good educations that equip them for the jobs of the future. Those are all agenda items that would help alleviate some of those economic pressures and dislocations that people are experiencing. The problem was I couldn't convince the Republican Congress to pass a lot of them.

Since I've been in the Senate, is that my work with people like Tom Coburn on opening up transparency in government, making sure that every dollar the federal government spends that's out there - that that's all posted on a searchable database on the Internet.

I think the American people can change Washington. But I think that it is not going to change, because somebody from on high directs that change.

When the economy is still struggling, putting people back to work, finding ways to spur economic activity, ultimately can help to reduce the structural deficits and debts that countries experience.

Part of the power of the Internet is that information flows out there and it's generally not censored and it's generally not controlled by any single authority.
