04 October 2012 Mitt Romney brought his campaign for the White House back to life today with a surprise victory over Barack Obama in their first live TV debate. His spirited, pugnacious performance was seen to have earned a clear win over the President, who appeared listless, disengaged and lacking in any killer lines. The 90-minute debate, watched by 60 million people, had an immediate impact on betting, with bookmakers slashing the odds on a Romney win from 5/1 to 11/4 in hours. The rival camps will now be waiting tensely to see if the opinion polls also shift.
