"Senator Obama, I'm not George W Bush." Watch highlights from Republican John McCain's latest confrontation with his Democrat rival Barack Obama. Snap polls showed Barack Obama to be the winner of the third and final presidential debate last night, in which the candidates clashed over the economy and other domestic issues. A national CNN poll showed 58 per cent of viewers thought the Democratic presidential candidate trumped his rival, Republican John McCain. Only 31 per cent thought McCain put in the better performance. An Ohio plumber became an unlikely star of the debate, with McCain talking directly to Joe Wurzelbacher, who was filmed at the weekend asking Obama whether he would lose out from the Democratic senator's tax plans. McCain said Wurzelbacher "wants to buy the business that he has been in for all of these years, worked 10, 12 hours a day". "Joe, I want to tell you, I'll not only help you buy that business that you worked your whole life for and be able - and I'll keep your taxes low and I'll provide available and affordable health care for you and your employees," said McCain.
