A few snippets from Friday night's presidential debate at the University of Mississippi between Sens. John McCain, R-Ariz., and Barack Obama, D-Ill.

"We've got to make sure that we're competing in education. We've got to invest in science and technology. China had a space launch and a space walk. We've got to make sure that our children are keeping pace in math and in science." - Obama

"We're going to have to rebuild our infrastructure, which is falling behind, our roads, our bridges, but also broadband lines that reach into rural communities. Also, making sure that we have a new electricity grid to get the alternative energy to population centers that are using them." - Obama

"I have a fundamental belief in the goodness and strength of the American worker. And the American worker is the most productive, the most innovative. America is still the greatest producer, exporter and importer. But we've got to get through these times, but I have a fundamental belief in the United States of America. And I still believe, under the right leadership, our best days are ahead of us." - McCain
