He [Barack Obama] might have a pen, and he might have a phone, but what he does not have is the constitutional power to run this country like a dictator.

I've been struck by how hungry we all are for a different kind of politics. So I've spent some time thinking about how I could best advance the cause of change and progress that we so desperately need.

Evil does exist in the world. A non-violent movement could not have halted Hitler's armies. Negotiations cannot convince al Qaeda's leaders to lay down their arms. To say that force may sometimes be necessary is not a call to cynicism - it is a recognition of history; the imperfections of man and the limits of reason.

We now live in a world where the most valuable skill you can sell is knowledge. Revolutions in technology and communication have created an entire economy of high-tech, high-wage jobs that can be located anywhere there's an internet connection. And today, a child in Chicago is not only competing for jobs with one in Boston, but thousands more in Bangalore and Beijing who are being educated longer and better than ever before.

I do think that I am generally optimistic.

One of the things that I am concerned about is the degree to which we've seen a lot of commentary lately where there were, there are Republicans or pundits or cable commentators who seemed to have more confidence in Vladimir Putin than fellow Americans because those fellow Americans were Democrats. That cannot be.

Rather take that moral sense and apply it to the particulars of a job that is going to test those ethical and moral precepts differently than if you're a professor, or a business person, or a dad. And if I were not comfortable with the judicious use of our military to protect the American people, than I shouldn't have run for president. And having said that, I do think that the wisdom of a [Martin Luther] King or a [Mahatma] Gandhi can inform my decisions.
