NBC News' White House producer Scott Foster tweeted:
Governor Romney has arrived at the University of Denver for tonight's debate.
The US unemployment rate has edged down to 8.1% nationally but any failure to continue that momentum will be seized upon by Republicans.
The lackluster debate performance from Obama, who has been called the greatest communicator since Reagan, gave us our October surprise.
The dust is settling on a successful night for Mitt Romney but the show must go on.
