CNN Political Director Mark Preston on second presidential debate: 'so much on the line'

The highly anticipated second presidential debate is just one day away. President Obama and GOP nominee Mitt Romney will face each other at Hofstra University tomorrow and poll numbers show that the race is as tight as ever. CNN Political Director Mark Preston is on the scene of tomorrow’s debate and joins us live with more.

“It certainly is close,” Preston says. There is “so much on the line right now. Mitt Romney’s hoping to turn in another strong performance, much like he did two weeks ago. Well, President Obama has to make up for that lackluster debate he had.”
