Governor Romney, what is the greatest long-term threat to the U.S. economy?

Mr. Romney: Our sense of optimism. America has to be optimistic and recognize that there's nothing we can't overcome. We face extraordinary challenges, absolutely.

We face jihadism, the emergence of Asia as a competitor, our overspending, our overuse of oil, the failure of our health care system. And yet we can't be burdened down with that. We have to recognize that what we have, as Americans, is the envy of the world.

We have technology. We have innovation. We have great schools. We have great families.

We have great homes. What we need to have is leadership that will tell us the truth, lay out the vision of where we can go, and actually lead.

And I want to be able to do that for America.
