Obama had an 'off night' on first debate

Asked what happened in the first presidential debate, when President Obama gave a weak performance, he told The Daily Show with Jon Stewart:

Obviously I had an off night. The presentation wasn't the way it needed to be but the issues haven't changed. They didn't change after the first debate and they didn't change in the second debate and that is, the stakes in this election are really big. Governor Romney makes a good presentation but the fundamentals of what he's calling for are the same policies that got us into this mess, that we've been fighting against for the last four years.
