65.6 million people watched the second Presidential debate. Now both campaigns are waiting to see if the polls shift over the next 24 hours.
U.S. voters say President Barack Obama won the second debate against Republican rival Mitt Romney by a 15 point margin, according to a Reuters/Ipsos poll.
Forty-eight per cent of registered voters gave the victory to Obama, while 33 percent gave Romney the win in Tuesday's debate.
The online poll found Obama's "favourability" rating rose five points to 55 per cent.
Romney's rating fell two points to 48 per cent.
The Republican surged ahead in polls following the first debate, but his lead was already on the wane ahead of the second, which was held at Hofstra University in Hempstead, New York.
Voters in Obama's home city of Chicago said they are pleased with President Obama's performance in last night's presidential debate. His supporters said they were heartened by his more confident performance. Self-described swing voter Scott Smith said:
"I like to see someone fight back, it was nice to see the host fact-check and see Obama fight for his dignity"
