Mitt Romney accused Barack Obama of a tendency to "say things that aren't true" yesterday, as the Republican challenger came under mounting pressure from a series of polls that showed him trailing in key battleground states.
After a week in which Mr Romney was heavily criticised by members of both parties for political point-scoring following the death of Chris Stevens, the US ambassador to Libya, the former Massachusetts governor said he was now looking forward to locking horns with Mr Obama in next month's first Presidential Debate.
"I think the challenge that I'll have in the debate is that the president tends to -- how shall I say it? -- say things that aren't true," he said in an interview with ABC News.
Mr Romney, who has been practising hard for the debates, added that he was still undecided on how best to tackle his opponent.
"It's difficult to say, well, am I going to spend my time correcting things that aren't quite accurate? Or am I going to spend my time talking about the things I want to talk about."
Although Mr Romney is trailing Mr Obama by just 3.2pc nationally, a new poll yesterday showed him trailing dangerously in the pivotal swing states of Ohio, Florida and Virginia, which analysts say he must win at least two out of three if he is to win.
According the NBC News/WSJ/Marist Poll survey, Mr Obama was up seven points in Ohio (50-43), five in Virginia (49-44) and five in Florida (49-44). The Romney campaign countered that the survey, which was taken after the Democratic Convention, reflected the 'bounce' Mr Obama was expected to get.
Mr Romney said he was unconcerned, predicting that polls would "bounce around" a lot before November 6.
"I'm ahead in a lot of other states, too. I saw one this morning, ahead in Florida, ahead in North Carolina. Gosh, we're even tied in Wisconsin," Mr Romney said. (©Daily Telegraph, London)
